We propose an analytical method for calculating the parameters of quasi-phase matching generation of the anti-Stokes component at stimulated Raman scattering in layered media. We present the results of the analysis in CIA considering losses and changes in the phases of all interacting waves. We consider frequency conversion processes in a layered structure consisting of periods of a “lattice” of modulation of the nonlinear susceptibility. Moreover, the values of the complex amplitudes of the pump radiation and the scattering components at the output of each layer are the input values of the corresponding complex amplitudes for the next layer. We give analytical expressions for the intensity of the transformation into the anti-Stokes component. We analyze the factors that limit the efficiency of the frequency conversion process. We calculated the maximum conversion efficiency to the anti-Stokes component in compressed hydrogen for a three-layer structure.

We propose an analytical method for calculating the parameters of quasi-phase  matching generation of the anti-Stokes component at stimulated Raman scattering in layered  media. We present the results of the analysis in CIA considering losses and changes in the phases  of all interacting waves. We consider frequency conversion processes in a layered structure  consisting of periods of a “lattice” of modulation of the nonlinear susceptibility. Moreover, the  values of the complex amplitudes of the pump radiation and the scattering components at the  output of each layer are the input values of the corresponding complex amplitudes for the next  layer. We give analytical expressions for the intensity of the transformation into the anti-Stokes  component. We analyze the factors that limit the efficiency of the frequency conversion process.  We calculated the maximum conversion efficiency to the anti-Stokes component in compressed  hydrogen for a three-layer structure.
