摘要：
In this paper, the influence of beam quality, transverse intensity distribution and atmospheric thermal lens upon laser-materials processing quality is studied. And the demand of flying optics on beam quality is analyzed. A new concept - laser processing range is proposed on account of beam quality. In order to gain the maximum laser processing area, the beam waist should be transformed to the center of the processing area. Or a good quality laser beam or optical path compensation and focusing system should be used. As well as the method of eliminate the atmospheric thermal lens is also obtained.
