Accounting for Transverse Inhomogeneity of Radiation Beams in Laser Raman Scattering

A simple method of accounting for transverse inhomogeneity of the pump and Stokes radiation beams in the description of stimulated Raman scattering (SRS) using intensity-transfer equations for interacting beams is proposed. Features of the method are illustrated using the calculated dependences of the Raman laser effi ciency on the output mirror refl ectivity and the pump pulse energy as examples.
