摘要

PPROBLEM TO BE SOLVED: To provide a laser beam machining method in which debris left unsublimated on a machining surface by ablation can be cleaned simultaneously with the ablation and in which no HAZ is caused in a workpiece. PSOLUTION: In the laser beam machining method (a method of performing ablation on a workpiece using a laser beam), the laser beam is pulsed light of optical vortex laser beam, wherein the pulse width of the pulsed light is 10 pico-to 100 nano-seconds. In this laser beam machining method, the laser beam used is the pulsed light of circularly polarizing/optical vortex laser beam in which the rotating direction of the circularly polarized light is the same as that of the optical vortex laser beam, wherein the circularly polarizing/optical vortex laser beam in use has the pulse width of the pulsed light ranging from 10 pico-to 100 nano-econds.

要解决的问题：提供一种激光束加工方法，其中可以通过烧蚀同时清洁由于烧蚀而未升华残留在加工表面上的碎屑，并且不会在工件中引起热影响区。

解决方案：在激光束加工方法（一种使用激光束对工件进行烧蚀的方法）中，激光束是光学涡旋激光束的脉冲光，其中脉冲光的脉冲宽度为10皮微-到100纳秒。在这种激光加工方法中，所使用的激光束是圆偏振/光涡旋激光束的脉冲光，其中圆偏振光的旋转方向与光旋涡激光束的旋转方向相同。使用中的光学涡旋激光束的脉冲光的脉冲宽度范围为10皮微秒至100纳秒。
