Abstract
The performance of longitudinally pumped Nd:YAG (YLF, Cr:GSGG) using 0.8 μm light was evaluated before and after exposure to 60Co gamma radiation. The host materials included in this study were YAG, Cr:GSGG, and YLF. The cw unirradiated optical-to-optical slope efficiencies for Nd:YAG and Nd:YLF were 63% and were found to degrade to 50% and 36% after 600 kRads of irradiation.
