Abstract

We show that effect of light-induced focusing of the low-frequency Raman scattering components and defocusing of the high-frequency components in the field of a gaussian exciting beam lead to a slight shift of the enhanced Raman line relative to the center of the spontaneous Raman line on the low-frequency side. We propose and provide a rationale for an efficient algorithm for calculating the average power for enhanced Raman scattering, based on numerical solution of the wave equation for the field of the Stokes beam developing from spontaneous Raman scattering.
