Thermal Shock Effect on Optical Films Damage Induced by High Power Laser

[in Chinese]; [in Chinese]; [in Chinese]

Abstract

The sectional temperature and stress diStribution of optical films under high power PUlse laser irradiation are calculated.Thermal shock effect was analyzed. Experiment of damage induced by a Q switched 1. 06 μm laser to a ZrO2 single film reveals the thermal shock damage process and mechanism.
