✦ Synopsis

The damage probability and damage morphology of the multilayer dielectric films under two wavelengths simultaneous irradiation are investigated. The damage morphology result shows that both pit number and depth caused by simultaneous 1ω and 3ω irradiation increase sharply compared with 3ω irradiation alone. The damage probability results demonstrate that the damage probability magnification ratio of the coupled wavelengths is bigger than 1, especially when 1ω and 3ω all held at near LIDT, the magnification ratio of the damage probability is 7-8, and these results are similar to a recent muti-wavelength damage study about KDP crystal.
