Paper Abstract

A concept for a solar-powered laser is presented which utilizes an intermediate blackbody cavity to provide a uniform optical pumping environment for the lasant, typically CO or C02 or possibly a solid state laser medium. High power cw blackbody- pumped lasers with efficiencies on the order of 20% or more are feasible. The physical basis of this idea is reviewed. Small scale experiments using a high temperature oven as the optical pump have been carried out with gas laser mixtures. Detailed calculations showing a potential efficiency of 35% for blackbody pumped Nd:YAG system are discussed.
