摘要
激光导致的损坏实验在一台大孔激光设备上被执行。严重损坏在前面表面和六个裂缝上的稠密的坑或者在前面和后面的表面定位了礼品的一个大孔的熔化硅石栅栏上被观察。关于栅栏上的损坏的古怪事实是损坏坑不同于另外的光学，几乎在前面表面上。根据观察，损坏现象由于散布的刺激 Brillouin (SBS ) 是效果发生在栅栏，它包括横向的 SBS，背 SBS 和之字形 SBS。[从作者抽象]
Laser induced damage experiment is carried out on a large aperture laser facility. Severe damage is observed on a large-aperture fused silica grating which presents dense craters on the front surface and six cracks alternatively located at the front and the rear surface. The bizarre fact about the damage on the grating is that, unlike other optics, the damage craters are almost on the front surface. According to observation, damage phenomenon is due to the stimulated Brillouin scattering （SBS） effect occurring in the grating, which includes the transverse SBS, the back SBS and the zigzag SBS.
