Abstract
High power laser facility for ICF will routinely operate at high fluence level. The damage on the large-area FOA optics is a key lifetime limiter. The optics should be checked after each laser shot for damage initiation and growth. On-line monitoring equipments are installed for this purpose. Damage pictures of a fused silica component are successfully taken and the luminance of the pictures could reflect the deterioration of the operational environment. Damage initiation and growth behaviors at 351nm high-fluence laser were observed. Damage density and damage growth are exponential with the shot number and some conclusions could be drawn. These results bring forward demands for future monitoring equipments and more experiments to establish a lifetime model.
