Raman shifting of long-pulse-length XeF* laser radiation

Abstract

Experiments have been carried out to Raman-shift long-pulse-length XeF* laser radiation in high-pressure molecular hydrogen. Typical output from a one-meter-long, e-beam-pumped XeF* laser was 0.6 J in 0.4 μsec. Significant Raman conversion, primarily into first Stokes radiation, was observed throughout the pump pulse, with an overall energy conversion efficiency of approximately 35%.
