Effects of localized CO2 laser damage repair on downstream beam qualities

摘要：

The diffraction patterns as a function of propagation distance from different parameters of CO2 laser repair cater are calculated by using a fast-Fouriertransform beam propagation code. The results show that the outer rim of sites leads to laser focusing and causes the more intense downstream modulation, the depth of cater affect the intensity of peaks slightly, and the diameter of cater has no influence on the intensity of peaks. By controlling the rim structure of the mitigation sites, downstream modulation introduced by CO2 laser repair cater can be declined and decreases the optics damage risk effectively.
