Both the spatial growth rate of stimulated Raman scattering and conversion efficiency to Stokes radiation were measured in three liquids (methanol, ethanol, and acetone) in the regime where the pump pulse is significantly depleted. Self-focusing was present, and, when taken into account by model calculations, the region of maximum Stokes spatial growth is in agreement with experiment. Conversion efficiency to first Stokes was measured for both focused and unfocused pump beams in liquid HC1 and is in agreement with the depleted beam model.
