摘要
Simulated Raman scattering in H-2 has been investigated with circularly, linearly, and randomly polarized XeCl laser pulses by varying H-2 pressure. The effects of pump radiation polarization and focusing geometry on Raman conversion to rotational and vibrational lines have been investigated. It is shown that circularly polarized pump pulses, high-angle focusing geometries, and/or low Raman medium pressures favor the conversion to purely rotational lines, as a consequence of gain suppression effects on vibrational scattering.
