Nonstattonary stimulated raman scaterring: three-dimentional model and method of the numerical solution

Three-dimentional semiclassical model is described for the nonstationary stimulated Raman scattering (SRS). The system of equations of the SRS of the rectangular pulse in the cylindrical sample is numerically solved by using the integral representation, when the laser-pump depletion and the delay effects are ignored. The pulse-shape of Stokes radiation is calculated for the various Fresnel numbers.
