Intense backward Raman lasers in CH(4) and H(2).
The conversion efficiency of the first Stokes radiation generated by backward stimulated Raman scattering is measured in CH(4) and H(2) 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 CH(4) is a better Raman medium than H(2) at moderate pressures (a few megapascals) to efficiently generate backward Raman lines.
