Efficiency of anti-Stokes generation in nonstationary stimulated Raman scattering

Nonstationary SRS equations are solved analytically for short samples in the approximation of a prescribed exciting field, and numerically for a longer medium taking into account the pumping depletion. The dependence of the energy of Stokes and anti-Stokes waves on their spatial mismatching is studied. The optimal angle of anti-Stokes generation is determined as a function of the length of the system, pump pulse energy, and the rate of transverse relaxation.
