Higher-Stokes-order Raman conversion of XeCl laser in hydrogen.
Efficient XeCl-laser Raman downconversion has been demonstrated with a novel oscillator-amplifier system based on higher-Stokes-order generation in H(2) gas. Simultaneous generation of the first (353-nm), second (414-nm), and third (499-nm) Stokes outputs has been observed in a Raman amplifier at energy-conversion efficiencies of 18, 22, and 14%, respectively, in good agreement with computer simulations.
