Abstract
In this work, we will review and evaluate the laser-induced optics damage observed on the final compressor gratings of the Advanced Radiographic Capability (ARC) laser. Damage initiation and growth rules are derived from online inspections and both measured and modeled laser performance are compared to a laser damage performance assessment of compressor grating witness samples performed offline. In addition, we will report the result of adapting these damage and growth rules to conditions relevant for the Scalable High-average-power Advanced Radiographic Capability (SHARC) 10 Hz Petawatt laser concept.
