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.
