Paper Abstract

Laser damage performance of K9 glass and fused silica glass were tested respectively at same experimental condition with 1064 nm nanosecond laser. The initial damage threshold (IDT), the damage growth threshold (DGT) and the damage growth laws of the two optics glass were investigated comparatively. The results show that the damage growth behavior of the two glasses are quite different, for example, the lower damage growth threshold and the higher damage growth coefficient for K9 glass, which can attribute to the difference of the material's damage morphology, optical absorption, residual stress near damage site between the two optics glass. The research is very important to choose transparent optical material applied in high power laser.
