Damage threshold of fused silica
WebFUSED SILICA WebApr 1, 2024 · The laser R-on-1 test protocol [27] was used to measure the laser damage threshold of fused silica surfaces. We incrementally ramped the laser fluence (~0.5 J/cm 2) at a repetition frequency of two shots per fluence until the damage occurred.Subsequently, another new site was shot again likewise. The experiment was …
