Paper Abstract

We review the magnitudes of the damage thresholds of practical optical materials, surfaces, and coatings found useful in short-pulse CO2 fusion lasers and discuss the materials properties and laser parameters that affect the thresholds. The optics used in the eight-beam, 10-kilojoule, 20-terawatt, Helios system at Los Alamos are used as specific examples. Among the optical components that characterize the Helios system are NaCl windows up to 41 cm in diameter, diamond-turned copper mirrors of similar size, CdTe Pockels cell crystals, germanium saturable absorbers and polarizer plates and multilayer-coated ZnSe partial reflectors.
