| Abstract: | The surface damage thresholds of K8 glass and Nd glass exposed to 2 ns large size high power laser are measured with a Nomarski polarized light interferometer, and the damage mechanism is studied. The ultrasound wave induced by the stimulated Brillouin scattering(SBS) is found to dominate the damage at the nanosecond pulse laser radiation. |
