摘要: Damage points induced by 355 nm laser irradiation increase more quickly on the surface of fused silica in vacuum about 10−3 Pa than atmospheric air at same fluence. The larger concentration point defects is confirmed photoluminescence intensity. X-ray photoelectron spectroscopy and infrared absorption indicate formation sub-stoichiometric surface. degradation mechanism discussed.
