Gas Cooled Slab (GCS) Scaling Laws and Representative Designs

摘要

Based on simple considerations for the mechanisms limiting average power operation of solid state lasers, we deduce some scaling laws for the gas cooled disk amplifier architecture. We discuss geometrical issues, gain and efficiency considerations, and output power scaling. The paper concludes with an outline for a high repetition rate GSGG system and a very large average power module suitable for a fusion driver. 8 refs., 4 figs., 5 tabs. (ERA citation 14:025025)
