Detailed results are presented of a high-efficiency Raman conversion of a 1-J XeCl excimer laser with an unstable resonator. We had 90% photon conversion of 18-MW-power XeCl laser radiation with 39% photon efficiency to the third Stokes order at 499 nm. The effects of rare-gas concentration in a H{sub 2}--rare-gas mixture on the Raman conversion characteristics were investigated. Finally, stimulated Raman scattering between the excited states of H{sub 2} at high gas pressure was observed, and conditions for generating these lines are discussed.
