摘要
报道了应用诺曼斯基(Nomarski)偏振光干涉仪测量K8玻璃和掺钕硅酸盐玻璃材料在高功率大口径激光照射后破坏阈值,并分析了破坏机理。发现在纳秒脉冲激光作用下。
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.
