Paper Abstract

Based on the theoretical model of uniform pulsed laser beam irradiating on the optical material, the stress distribution of the transparent material when laser with different beam spatial distribution - circle beam spot and dark-cross beam spot - irradiated to the inner of optical material was discussed. The experiment that 532nm Q-switched laser pulse was focused to the inner of silicate glass was taken, which the beam spatial distribution of the output laser was dark-cross beam spot. According to the theory, the experimental results and phenomena were analyzed and the damage micro-configurations were explained. The theory and experiment could be accordant well.
