Abstract

Laser induced damage experiment was carried out on a large aperture laser facility. Severe damage has been observed on a large-aperture fused silica grating which presented 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 happened in the grating.
