Abstract

UV laser damage is still the key issue of high power nanosecond laser systems. The operation performance of the final optics in SGII-UP facility is first reviewed. Based on a high power laser prototype, laser-induced damage of large aperture final optics at 351nm was experimentally studied, including damage initiation, growth and morphologies. The near filed of 351nm laser beam was precisely measured with a high resolution by using the precision diagnostics system (PDS) to study the effects of laser modulation and propagation on laser damage. The damage behaviors were comprehensively analyzed and the main contributors to laser damage were discussed. The development perspective of final optics system for high power laser system is briefly introduced.
