Abstract
The conversion efficiency of the first Stokes radiation generated by backward stimulated Raman scattering is measured in CH4 and H2 that are pumped by a third harmonic of a Nd:YAG laser in the 12–55-mJ energy range and in the 0.86–6.00-MPa pressure range. Our experimental results show that CH4 is a better Raman medium than H2 at moderate pressures (a few megapascals) to efficiently generate backward Raman lines.
