Abstract
We took into account the generation of high-order Stokes and anti-Stokes components in our method of anti-Stokes generation at stimulated Raman scattering in a medium exhibiting variations of the third-order nonlinearity along the direction of propagation. The dependence of Raman gain dispersion on quasi-phase matching conditions was studied by numerical simulation. The possibility of effective periodical quasi-phase matching structure realization for hydrogen was determined. We received the multiwave models of media in which the efficiency of first anti-Stokes generation reached ~40%. The results of our research can be used for creation of new effective nonlinear-optical frequency converters and Raman amplifiers.
