Efficient XeCl/H2 Raman shifting to a blue-green region

Abstract
90% photon conversion of 18 MW (1 J, 55 ns) power XeCl laser radiation to Raman Stokes beams is reported with 39% photon efficiency and ∼60% peak power conversion efficiency to the third Stokes order S3 (499 nm). Relaxation oscillations of higher order Si(i≥3) pulses have been observed.
