Spectral-angular competition of stimulated Raman scattering and parametric processes under self-focusing

Abstract

In this work, physical prerequisites to the manifestations of the competition of Raman and parametric processes in the formation of the spectral-angular structure of higher anti-Stokes components under the conditions of self-focusing (SF) are considered, and experimental results on the observation of the competition effect in generation of the second anti-Stokes SRS component in toluene are presented.
