Role of the parametric and Raman processes in the generation of the second axial Stokes component of the stimulated Raman scattering

The mutual influence of the parametric and Raman mechanisms in the generation of the higher Stokes components of the stimulated Raman scattering is investigated theoretically and experimentally for the case of the second axial Stokes component. It is shown that the experimental results can be explained if allowance is made for the parametric mechanism even in the presence of considerable wave mismatch.
