The results of experiments on SRS conversion of XeCl-laser radiation in hydrogen and lead vapors with different pump-beam divergence are presented. It is shown that the conversion efficiency is limited primarily by optical breakdown, whose effect increases as the energy and divergence of the converted radiation increase. The total quantum efficiency for conversion of XeCL-laser radiation with a divergence of 0.1 mrad in hydrogen was ~90%.
