Ultrafast Laser for Glass Processing

The special performance of the glass makes the glass processing is facing greater challenges, ultra-fast burning laser applications will bring what breakthrough?

Glass is a transparent solid material that has the unique properties that other materials do not possess: it has excellent optical properties, can reflect, bend, transmit and absorb light, even beyond the entire visual range, High transparency; from the chemical properties, the glass is a corrosion-resistant inert material, can be used as a container for many chemicals. From the thermodynamic and power aspects, the glass is a great insulator. From the physical performance point of view, the glass surface hard, scratch-resistant wear, in recent years through a variety of methods, glass and even have the flexibility. However, it is these properties that make glass processing more challenging, for example, once the glass has excellent tensile strength, it becomes fragile.

Usually a small crack will cause the glass to break. Once the microcracks are formed in a part of the glass, it will spread to the edge of the glass, causing rupture. This fragile property of the glass makes it difficult to process. On the other hand, the evolving technology allows it to be made into smaller, and different shapes of glass for use in different areas. Traditional precision methods such as lithography and electron beam lithography to process glass, but these techniques are too expensive to operate, especially for large areas. Today, high power laser pointer technology provides the most accurate way to process glass. The most straightforward way is to use a single photon absorption in the wavelength range, the glass in the infrared or ultraviolet light will not be highly transparent.

However, direct absorption can cause problems, including poor thermal effects and the formation of heat affected zones, which can produce microcracks that seriously compromise the mechanical stability of the glass. In addition, the bottom of the glass surface processing, manufacturing three-dimensional structure, the need to use high transparency wavelength. Although nanosecond pulsed lasers can be used to create subsurface structures in glass, the physical mechanism of the glass will limit the fineness of the microprocessions and produce microcracks.

In recent years, an exciting alternative process has been put into industrial applications, that is, ultra-fast green laser light in the near infrared wavelength range generated sub-second pulse. In this method, the ultrashort pulse is closely focused on most of the glass or surface, and the power density per square centimeter exceeds the number of tiles, causing complex and diverse processes such as simultaneous multiphoton absorption, avalanche and collision ionization, resulting in a glass The matrix is highly localized by the destruction while almost no energy deposition (only a few microfocus or less). Since the energy used for each pulse is extremely modest, the thermal effect on the part (or even the volume of the focus) is negligible. This method is often referred to as "cold ablation" and can be used to make extremely accurate 3D structures. Compared with other micro-manufacturing technology, femtosecond laser micro-manufacturing transparent material has a unique advantage.

The Shortcoming of Traditional Laser

As the next generation of display technology, laser display is also subject to the scientific and technological community, the business community of common concern. Compared with the traditional display technology, laser display from the high brightness, clarity, color gamut, color saturation, life and other aspects have a leading edge, highly industrial prospects; many Chinese companies have set off a green laser pointer TV hot, related products Has been listed. From the root, white light laser light source research and development, is the fundamental premise of white laser applications.

The laser is produced by the expansion of the stimulated emission, with good monochromaticity, spatial coherence and temporal coherence, good directionality and high brightness. These four characteristics of the laser show that the laser has a high coherent light intensity in a large coherent volume. Coherence is an important feature of the laser. Conventional laser and white laser, we exclude monochrome (because the white light is not monochromatic), all the laser must have good coherence, direction and high brightness characteristics, can be called laser.

John Ballato focuses on the improvement of light performance, he is looking for fiber materials that will not reduce the blue laser pointer. Has been manufactured to meet the basic performance requirements of the fiber, follow-up will continue to optimize to meet the next generation of high-power laser system requirements. And Lin Zhu is more focused on improving the efficiency of laser pumping, and thus create a strong direction of the laser beam. Although their projects are carried out separately, but for the laser power boost are actively trying. This will also promote the application of high-power lasers, whether in the military or in the industrial sector.

In addition to the above methods, photonic crystal fiber white light lasers can also produce high-power, broadband and ultra continuous white light lasers. Its white light laser is mainly used in the field of photocurrent microscopy, nano photonics, fluorescence spectroscopy and imaging, super-resolution imaging, optical coherence tomography and many other fields. The characteristics of traditional laser not with white light laser, the shortcoming of traditional laser; change and development of white light laser source can bring more fields, and produce new scientific fields, as well as new applications; therefore, it will inevitably become the object of many scientists of the chase.

Due to the laser generated laser restrictions, resulting in a good 10000mw laser monochrome characteristics, but it has become a laser in the field of application of the short board; laser can not produce any wavelength of the laser, can not produce supercontinuum, ultra-wideband laser The In the field of laser applications, people have different requirements for the frequency (or wavelength) of the laser, and this time with the help of nonlinear crystals. But many bands of laser still can not be created.

Laser Plasma Accelerators

In this latest work, John Doyle and colleagues at Harvard University have now cooled the three-atom hydroxyl strontium molecules, named after the Greek hero Sisyphus, who was forced to push a boulder onto the top of the hill, Roll down and then often resemble this work forever. Sisyphus cooling process is the molecule through the "climb" by the laser standing waves generated by the potential energy loss of kinetic energy process.

The accelerator works by projecting a high-energy, high-brightness burning laser pointer beam onto a thin metal foil target with an area of only a few square microns. "The energy of the laser pulse is large and the energy of the generated electromagnetic field is even more than an order of magnitude greater than the coulomb force inside the atom," Hidding explains. "The metal foil target is therefore instantaneously converted to a plasma." The plasma particles are strongly excited by the laser and other plasma field acceleration, the degree of acceleration depends on the initial position of the particle, this process can produce huge energy.

With the laser to the atomic gas cooled to ultra-low temperature, first appeared in the late 1970s, completely changed the material quantum state of the study. The first Bose-Einstein condensate was manufactured in the laboratory in 1995. The first Fermi-Dirac condensate was created in 2003 as two important milestones for this technology. The technique relies on the fact that the photon carries a small amount of momentum, and under certain conditions, the atomic reabsorption and re-emission of the photon can reduce its random motion and thus reduce its temperature.

Space radiation in outer space is replicated in the laboratory. Scientists use 5000mw laser pointer plasma accelerators to replicate high-energy particle radiation around the Earth. The study can help scientists to study the impact of space exploration on human beings, and for the development of satellite and rocket equipment to provide a strong guarantee.Space radiation is a major obstacle to human exploration of the solar system. High-energy ionized particles of the sun and deep space are extremely dangerous to human health, and they can penetrate directly through the skin and deposit energy, causing irreversible damage to cells and DNA. In addition, space radiation can cause serious damage to satellite equipment.

Glass Laser Engraving

The glass is easily broken during the engraving process, so the glass engraving must be very careful. For different types of glass, lead content is different, its engraving methods are not the same. With the increase in lead content, glass hardness, high temperature viscosity and so on, the glass is also more easily broken. Ordinary glass is usually easier to carve than crystal glass, because the crystal glass lead content is high, hardness viscosity decreases, increasing the difficulty of brightest laser pointer engraving. Glass laser engraving process: When the laser beam touches the glass surface, the glass surface heats up, the glass molecules fly. If the glass can not be cooled down, the heat generated by the potholes will be bigger and bigger, the final carving effect will be as bad as mud.

At present, there are many kinds of laser technology for glass cutting, and these technologies are implemented in a variety of ways. However, the main advantages of all these glass laser cutting techniques are similar. First, all laser cutting methods use non-contact machining, which greatly avoids the problem of fine cracks and debris. In addition, the residual stress left by the blue laser pointer cutting method in the glass is very small (the residual stresses of the different cutting methods are different), and thus the cutting edges are of higher strength. This is very important, if the residual stress is too large, then even in the center of the glass force, often also lead to the edge of the glass rupture. Therefore, compared with the use of mechanical cutting glass, laser cutting glass can withstand the force to one to two times larger.

Laser cutting can also reduce the number of process steps due to the need for (or no) the need for subsequent cleaning or grinding stages. Thus, although the cost of capital for laser cutting workstations is higher than that of mechanical systems, the total investment in laser cutting is lower than that of mechanical processing systems because no additional grinders are required. Due to the reduced demand for post-processing and cleaning work, the best burning laser pointer cutting method is more environmentally friendly than the mechanical method and consumes less water (or does not require water at all). Finally, some laser cutting methods support glass curve cutting. Today, the demand for curve cutting is growing, especially in the cell phone manufacturing industry, manufacturers want to produce more complex geometric shapes of the screen, including punching material to accommodate buttons, control keys, LED and camera lens.

CO2 and CO laser source processing glass are in the principle of local intensive heating. Specifically, all the glass is easily absorbed by the CO2 laser at a wavelength of 10.6 microns, so the focused laser beam can quickly heat the glass surface or near surface area. In order to achieve the cutting effect, the glass needs to be translated relative to the laser beam and the glass is rapidly cooled by the spray or jet above the glass. The resulting thermal shock causes the glass to form a continuous slit. If the glass is thinner, the slit can penetrate the substrate completely, thus completing the cutting directly, which is called "overall cutting". If the glass is thick, then you need an additional laser or mechanical breaking link to complete the cut, called "laser scribing."

The overall processing of the CO 1000mw laser pointer is roughly the same as above. However, the glass to the CO laser output 5 micron to 6 micron laser absorption rate is significantly reduced, which makes the laser irradiation of large pieces of material can penetrate deeper. Therefore, the heat can be directly into the large pieces of glass, without having to rely on the surface from the spread. Tests conducted by related companies show that this can further reduce the residual stress than using CO2 lasers, thereby increasing the strength of the cut workpiece while allowing the manufacturer to expand the processing interval. There is also an attractive advantage for CO lasers to support curve cutting. CO2 lasers are often confined to cutting the glass in a straight line because the circular output beam must be remodeled into slender light in order to better diffuse the high temperature produced on the surface. In contrast, the low absorption rate of CO lasers allows it to use circular beams directly without adverse thermal effects. In addition, CO lasers also support cutting chemical tempered glass.

The laser ablation of the glass processing mechanism is completely different from the CO2 and CO lasers that form slits by thermal shock. Laser ablation The way to achieve scribing is to actually remove the material by precision ablation. Abnormalization is achieved when a sufficiently large 300mw laser pointer is applied to excite the nonlinear absorption in the glass. In this way, the material can be removed by local intensive heating (hot ablation) or by direct destruction of interatomic chemical bonds (light ablation) through extremely high peak power.

Laser Processing Technology

The development of miniaturized, low-cost laser particle accelerators is the goal that scientists have always dreamed of. The ultra-short laser-driven tail-wave field accelerator has an ultra-high acceleration gradient of three orders of magnitude higher than that of a conventional RF accelerator, providing a new way to achieve miniaturization of high-energy particle accelerators, Radiation devices, free electron lasers and high-energy physics research will also have far-reaching impact.

Protons and other positive ions have a wide range of applications, including particle physics, materials processing and medical aspects. For example, proton beam therapy can be used to destroy some cancerous tumors at minimal damage to surrounding tissue. However, the actual use of protons and ion beams is subject to constraints that require a larger and expensive particle accelerator to produce a high quality beam source. By controlling the polarization of the incident 1mw laser pointer, the quality of the laser accelerating the proton beam can be improved, and the researchers have found this conclusion. This discovery can help physicists create compact proton beam sources for medical, lithography, and even astrophysics.

With the further study of the interaction between lasers and materials, laser processing technology will also be widely used in flexible manufacturing systems. The flexibility of the laser processing system mainly refers to the laser processing head can be flexible to guide the laser beam to reach the parts to be processed position. Dimensional laser processing, high power laser pointer three-dimensional processing is the future direction of the direction of development of laser processing, in order to achieve the flexibility of laser processing, three-dimensional laser must be in the direction of the laser processing machine, Using motion optical system. High-power three-dimensional YAG laser processing system is usually used robot (or robot) with optical fiber for beam transmission, by the robot holding the laser head to complete a variety of movement, the laser is transmitted through the optical fiber to the laser processing head, to reach the workpiece surface, which In the processing system, the beam transmission and focusing characteristics are not affected by the machining position.

In a separate experiment, the researchers irradiated the aluminum foil line with laser pulses, i.e., elliptically polarized light and circularly polarized light from the Gemini burning laser pointer. The pattern of the protons of different energies is significantly different: for example, in all polarized states, low-energy protons are concentrated in the center, but elliptically polarized and circularly polarized light are more compact in propagation than linearly polarized light. The high-energy protons produced by linearly polarized light are called double lobes, while circular and elliptically polarized light form a circular density distribution. The experimental observation of the pattern closely matches the computer simulation conclusion, and the existence of small deviations can be fully understood as experimental defects, the researchers explained.

The use of laser processing, not only processing speed, high efficiency, low cost, and to avoid the mold or tool replacement, shorten the production preparation time cycle. Easy to achieve continuous processing, laser beam transposition time is short, improve the production efficiency. Can be a variety of workpiece alternately installed. When a workpiece is machined, the finished parts can be removed and the workpiece to be machined is installed to achieve parallel machining, reduce installation time and increase the red laser pointer processing time. The laser itself is a relatively simple and easy to control device, if it produces the beam into a very fine light beam, you can cut; defocus can be welded; and then defocus a little, can be heat treatment.

The laser beam is driven by direct drive and guide. The laser can be used for rotation, tilt, up and down movement around the movement, the workpiece can be processed on the vertical surface and complex surface; and direct drive without air, high precision. The combination of 5mw green laser control and robots, with the robot to move or multi-axis way to flip the parts under the beam, can be processed with some traditional methods of processing more difficult parts. Take the multi-level rapid response of the anti-collision measures, beam guide device contact the workpiece, the movement system immediately shut down, so that the system is not destroyed, to avoid the expensive maintenance; collision can quickly and simply resume work, reducing the collision caused by downtime Time, improve the processing efficiency and reliability of the laser system.

Two - photon Excited Laser Scanning Real - time Stereomicroscope

Recently, the State Key Laboratory of Transient Optics and Photonics, the Institute of Optics and Precision Mechanics, Xi'an Institute of Optics and Fine Mechanics, Chinese Academy of Sciences (hereinafter referred to as "Transient Room") has successfully developed a two-photon excited strongest laser pointer scanning real-time stereomicroscope. Microscopic methods and high-resolution two-photon excited laser scanning fluorescence microscopy combine to achieve high-speed stereoscopic imaging of three-dimensional fluorescent samples and are authorized for national invention patents.

Contemporary life science research has made increasing demands for optical microscopy - higher spatial resolution, greater imaging depth, and faster imaging speed. Especially for biological in vivo microsurgery, the scattering of light from biological tissue greatly increases the noise, which seriously affects the spatial resolution and imaging depth. In order to improve the imaging depth, two-photon excited 300mw green laser scanning fluorescence microscopy technology has been widely used in the field of nerve imaging since the 1990s, but its imaging method of point-by-point scanning has seriously restricted the imaging speed. Because the depth of view of the high-resolution optical microscope is very small, it is necessary to complete the three-dimensional imaging of the sample, usually need dozens of layers or even hundreds of layers of two-dimensional image of the superposition of reconstruction, image acquisition and processing generally takes several minutes or even tens of minutes Fast and real-time acquisition and display of three-dimensional images is very difficult.

Transient chamber super-resolution imaging team under the leadership of the researchers Yao Baoli and Ye Tong, the binocular vision principle and the Bessel beam to produce the expansion focal field, proposed by the four galvanometer composed of burning lasers for sale beam stereoscopic scanning device, The control of the three positions of the Beerle beam and the inclination of the Bezier beam is achieved, which breaks the limitation of the traditional laser scanning with only two degrees of freedom. By means of the optimal design and control of the three-dimensional scanning device, the three-degree-of-freedom fast scanning of the Bezier beam can be realized, and the double-view angle can be switched on the order of milliseconds to solve the double- Optical path at the same time imaging technology, for the first time to achieve a real-time laser scanning based on dual-view stereoscopic imaging and display system. The system can be three-dimensional dynamic imaging of the sample and real-time binocular stereoscopic observation, the three-dimensional imaging speed than the traditional point-by-point scanning method increased by one to two orders of magnitude. The two-photon 200mw green laser stereomicroscope system provides a new observation tool for 3D real-time imaging and display of living organisms.

"It allows us to view the dynamic 3D microcosm in real time like watching a three-dimensional movie without the need for light slicing without the need for time-consuming three-dimensional image reconstruction." Yang Yanlong so summarized the characteristics of this system, he is responsible for the design and completion of the three Scanning and imaging the key parts of the display. "Binocular vision imaging is a very efficient way to obtain three-dimensional information, but the existing 100mw laser pointer stereomicroscope, spatial resolution and depth of field are mutually constrained, and we use three degrees of freedom to scan the Bezier beam for nonlinear fluorescence excitation to break through this limit."

This research has been carried out from the basic principle verification, the key technological breakthrough to the prototype prototype, and has experienced all aspects of basic research to application integration under the support of the "100 people program" and the National Natural Science Foundation of the Chinese Academy of Sciences. At present, the research group is working with relevant scientific research institutions at home and abroad to carry out biomedical application of 30mw laser pointer cooperative research, as soon as possible to apply the technology to the biological in vivo three-dimensional rapid imaging and display areas.

How to achieve laser + intelligent manufacturing?

What is the specific smart manufacturing, 100 companies may have a hundred solutions, but the core should be the concept of further sublimation of automation, until the flexible and intelligent. In the field of mechanical equipment, high power laser pointer processing equipment more easily automated integration, is the core of intelligent manufacturing equipment. Therefore, the laser and intelligent manufacturing how to perfect combination, is the future manufacturing upgrade important factor.

As the main provider of laser equipment, Han's laser in the field of intelligent manufacturing has long been the layout of its robot, machine vision, sensors, automation equipment and other intelligent, automated technology-related reserves of resources. Recently, Han's Laser Intelligent Equipment Group in Guangdong Province, Shenzhen, led the industry and more than the laser industry experts witnessed the opening, but also taken a step in the field of intelligent manufacturing.

In the specific application areas, Han's laser power battery manufacturing in the area of key layout. In the subsidy, limit number, environmental pressure and other factors under the influence of the electric car industry is booming. Its power source batteries, battery modules are the core components of electric vehicles manufacturing process to be introduced urgently, cheap laser pointer processing technology in this area promising. Han's vice president of huangxiang hu has said on many occasions, very optimistic about the future of laser technology in the field of power battery manufacturing prospects. According to Huang Xianghu introduction, Han's laser to build a new energy lithium equipment, closed-loop ecosystem.

At the beginning of 2016, Han's Laser Strategic Investment Holdings Dongguan Junzhuo Automation Technology Co., Ltd., which opened the Han officially entered the pack and module automation and equipment in the field of prelude. Subsequently, with the Shenzhen Municipal Science and Technology Co., Ltd. signed an agreement to invest in the acquisition of lithium batteries to achieve the welding and injection of seamless link. Since then, Han's Laser and Dongguan Zhuang Ling Automation Technology Co., Ltd. signed a merger agreement, which marks its entry into the field of lithium battery coating. In recent days, Han's new acquisition of Jin Fan Jin-fan laser, and further open up the power battery single, double coating equipment.

As a result, Han's laser successfully created a complete set of intelligent battery manufacturing solutions, but also for the green laser pointer technology into the field of intelligent manufacturing provides a good reference sample.

The Shape of the Photon Affects the Interaction of Light and Matter

Scientists at the National Center for Quantum Technology (CQT) at the National University of Singapore have revealed that the shape of a photon can affect its absorption by a single atom. They say the finding is significant, suggesting that the photon's energy, or 5mw laser pointer wavelength, is no longer the only factor determining photonic behavior.

CQT chief scientist Christian Kurtsiefer and his research team have mastered how to accurately control the photon shape. "We usually do not think that photons will spread in space and time, and have a certain shape, but the photons we use in our experiments are four meters long," he commented.

The results were published in the November 29 issue of Nature Communications, using rubidium atoms and infrared photons. Each emitting a photon to a single alkali metal atom. "Our experiments study the most fundamental interaction of light and matter," commented Victor Leong, a Ph.D. student who participated in the study.

It takes 13 nanoseconds for a 4-meter photon to pass through such atoms. Whenever a photon passes through an atom, the team looks at whether or not the atom is excited. By recording the excitation time, the researchers can get the photon atomic absorption of the probability of time-varying relationship.

Two kinds of photons with different shapes of brightness increase and attenuation are studied. Hundreds of millions of 200mw laser pointer measurements lasting more than 1500 hours show that for both types of photons they are just over 4% absorbed by rubidium atoms. However, if the time scale from nanoseconds, each time the photon absorption probability and the shape of the photon.

CQT's team found that if the photon reaches the atom, the photon intensity after the first weak and strong, then the peak atomic excitation probability than the photon brightness of the first strong case of more than 50% higher than weak.

Researchers envisioned atoms more likely to absorb energy-boosting photons, explains Matthias Steiner, co-author of the paper, explaining that "the natural process of releasing photons by stimulated atomic decay causes this phenomenon. Atoms release an attenuated photon, In turn, imagine that the form of the equation does not change and that atoms will naturally encounter photons with increased brightness, and that the photons we choose to shape are inspired by the time - reversal symmetry of quantum mechanics.

The research team believes that their work helps to understand the use of 400mw laser pointer light and material interaction technology, "such as quantum communication, sensors, computing and other quantum technology involved in the process, usually need to use information into the photon atoms. "In order to design reliable quantum devices, scientists need to control this interaction, and you can use it only if you understand the interaction," says Alessandro Cerè, co-author of the paper.

The main conclusions are as follows: "We found that the process of light scattering is related to the photon's envelope.With the exponential decay of the envelope shape of the photon with time exponentially increasing with time, the envelope shape of the photon can more effectively excite the atoms.Using the exponential rise Shape of the photon excited atoms, which in a narrower time interval to produce a higher peak excitation probability of such synchronization will help the quantum communication network connection.

Lidar is a Robot's Eye and Ear

For owners, radar ranging is not strange. When driving at high speed, the radar range allows the car to keep the distance between the car and the car, the car will automatically move forward, the owner can not step on the accelerator. Of course, the direction must be controlled by the owner. Moreover, the use of radar range, the vehicle can also detect the front of the vehicle, and maintain their own distance; when the car is too close, it will automatically reduce the speed. So it seems that, although the radar range does not liberate the driver's hands, but at least one foot Liberation (foot on the accelerator), it can be regarded as a pioneer unmanned. However, radar range is not just used on the car. Lidar is so good, why do robots rarely use 300mw laser pointer radar to avoid obstacles?

The radar is "radal English" abbreviation, radio method discovery state parameters of the target and determine their space positions, and the distance of the target, ask and speed is mainly composed of antenna, transmitter and receiver (including signal processor) and a display part. If it is a bit more popular, the radar is similar to the eyes or ears, of course, it is no longer a masterpiece of nature. The principle of measuring distance is as follows: measuring the time difference between the transmitted pulse and the echo pulse, because the electromagnetic wave travels at the speed of light.

There are many kinds of radar, and the classification method is very complicated. Military radar. Can usually be classified according to the purpose of radar, such as early warning radar, search radar warning radar, command, artillery radar, radar altimeter, battlefield surveillance radar, airborne radar, radio altimeter, radar fuze, weather radar, navigation, navigation and collision avoidance radar control radar and IFF radar etc..

According to the classification of radar signal, pulse radar, continuous wave radar, pulse compression radar and frequency agile radar; according to the classification of angle tracking mode, a single pulse radar, conical scan radar and concealed conical scanning radar; target classification according to the parameter measurement, measurement of two coordinate radar, Gao Lei, three coordinate the enemy radar and recognition of radar, multi station radar; radar frequency according to points, can be divided into radar, microwave radar, millimeter wave radar and 5mw laser pointer radar. The radar has a day and night can detect, block and not affected by fog, clouds and rain, has the characteristics of all-weather, all day long time, advantages, and a certain degree of penetration so that not only become the military indispensable electronic equipment, but also widely used in other fields, such as weather forecasting, resource exploration, environment monitoring, even related to scientific research, such as research objects, atmospheric physics, ionospheric structure research.

Now, radar ranging is also used in the industry of the most current - robotics. So, what is the role of radar in the field of robotics? At present, how to apply the rate?

The application of radar in the navigation of mobile robot is more and more. This is mainly due to the many advantages of the laser radar range measurement technology, compared with other distance sensors, it can take into account both the accuracy and speed requirements. Work in the infrared and visible light, green laser pointer beam radar work called laser radar is a radar system to transmit the laser beam to detect the target position and velocity characteristics, laser radar provides a good method for robot navigation.

Some robots are free to walk, they use a remote control or pre programmed. The robot's "true freedom walk" should be able to identify the obstacle, by turning and stop the realization of active avoidance, and achieve independent route planning, laser radar is an important method to solve the bottleneck of the popularity of the robot obstacle.

In order for a robot to walk, one must first see it - in addition to the algorithm, as well as the important hardware. Laser radar allows the robot to emit burning laser pointer target detection signal, and then received back from the reflected and transmitted signals are compared for proper treatment, information about the target, such as target distance, azimuth, altitude, speed, attitude and even shape parameters. In fact, the robot is positioning itself, positioning objects, as well as map building. A hands-on ability of electronic production, spent half a year to create a full range of radar attack robot". The use of ultrasonic ranging radar, not only to identify where the master's shoes, but also to the owner of the shoes.

At present, the application area of laser radar is the sweeping robot, which is mainly to achieve the purpose of obstacle avoidance and automatic path planning. Now a number of entry-level sweeping robot, in fact, the process is relatively simple sweep, mostly only with the ability to clean the N font, including the coverage area is difficult to assess the coverage. According to the sweeping robot experts said that the fundamental reason is that they can not see, can not walk freely. At this time, the laser radar has played the role of sweeping robot eyes, so that it can achieve the purpose of cleaning.

Laser radar is so good, why is the market rarely see the use of high power laser pointer radar robot?

At present, in the world, in addition to some Chinese enterprises, only a few companies, such as Japan and Germany have the ability to produce laser radar, but its price is not low. General service robots can not afford such an expensive component. So expensive is also a reason, the general laser radar technology in the development of a certain degree of difficulty. Technically, the precision is good and achieve millimeter accuracy is not easy, want to achieve this precision, a big problem: the process precision, to achieve long-distance mm level accuracy of optical measurement technology and in fact are required. In fact, the price of speed, traditional laser rangefinder is not expensive, Taobao may be a few hundred dollars could buy one, but its measurement speed is very slow, it may take a few seconds to complete, and the need to complete the measurement of 100mw laser pointer radar, thousands of thousands of times in a second. So the price of traditional laser radar is also very expensive.

What are the performance advantages of fiber laser cutting machine?

Fiber laser cutting machine is in recent years in the international market newly invented a new type of cutting machine, the cutting machine products in cutting speed, or in the mechanical volume have absolute advantage, today we mainly explain the main advantages of this cutting machine is reflected in what areas.

The new fiber laser cutting machine adopts the principle of cutting is a kind of high performance 300mw laser pointer cutter, laser ray emitted from the numerous high performance and high energy in the process of laser cutting, laser radiation generated by these huge energy, you can instantly cut surface evaporation, so it can easily be very hard interface removed. At present, this technology still belongs to a kind of cutting technology is the most advanced, without any other cutting process can surpass it, and this speed cutting process in cutting process is very fast, you can instantly be very thick steel plate and easy cutting, cutting accuracy is very accurate, the cross section of the cutting precision can reach several millimeters can fully meet the demand, cutting some high requirements.

The new fiber laser cutting machine adopts the principle of cutting is a kind of high performance laser cutter, laser ray emitted from the numerous high performance and high energy in the process of laser cutting, 50mw laser pointer radiation generated by these huge energy, you can instantly cut surface evaporation, so it can easily be very hard interface removed. At present, this technology still belongs to a kind of cutting technology is the most advanced, without any other cutting process can surpass it, and this speed cutting process in cutting process is very fast, you can instantly be very thick steel plate and easy cutting, cutting accuracy is very accurate, the cross section of the cutting precision can reach several millimeters can fully meet the demand, cutting some high requirements.

In the process we use fiber laser cutting machine, spread all the dissemination of information and energy is transmitted through optical fiber transmission, in this way the biggest advantage is to save a lot of manpower, light path any leakage phenomenon can not be generated in the transmission process. And before using the device without any adjustment of the light path, you can easily transfer energy to the laser.

The core components of the 5mw laser pointer cutter it is only one, that is the laser, and laser production volume is very small, not like other products of the same type as cutting occupy a lot of space, so that the overall mechanical volume will be reduced a lot, not in mechanical manufacturing or transportation process can reduce a lot of the manpower for us.
