摘要

The surface damage performance of fused silica under mono-wavelength configuration or simultaneous dual-wavelength exposures to 1053, 527, and 351 nm nanosecond-laser pulses is investigated in order to probe the mechanisms governing damage initiation during frequency conversion. Based on the absorption and heat transfer mechanism, coupled to laser damage statistics, a model considering the Gaussian distribution of irradiation intensity has been presented to obtain precise calculation result about laser damage probability. Laser damage probability curves are measured on the surface of fused silica with different wavelength configurations. By studying the influence of the laser wavelength configurations on the laser damage probability, we show with our methodology that the types of damage precursors under the irradiation of different wavelength configurations can be identified.
