Solution
Picosecond Laser Surface Ablation Cutting Principle
The high peak power laser beam is reflected under the movement of the scanning galvanometer, through the flat field scanning objective lens focused on the surface of brittle materials, scanning galvanometer control the laser beam to repeat the circular motion, gradually ablate the surface of the material, the material is rapidly raised by the high-density peak power laser instantaneous heating to the plasma gasification temperature, so that the material is gradually ablated by the laser and in the form of gas from the surface of the material to escape, so as to achieve the material through the separation.
