The fusion experimental lasers at Lawrence Livermore Laboratory, called Argus and Shiva, operate with very high fluence on the systems optics. The optical surfaces may be damaged by the laser beam both because of the limitations inherent in currently available bulk materials and coatings, and because debris contaminating the surfaces initiates damage. The damage thresholds which we have experienced on our operating systems are presented. A unique solution for recycling debris shields exposed to target microexplosions is also discussed. Comments on the development of improved damage thresholds are included.
