We present a new, to our knowledge, method of Stokes-anti- Stokes Raman amplification in fiber, based on our idea of anti-Stokes generation at stimulated Raman scattering in media with variations of third order nonlinearity ((chi) (3)) along longitudinal coordinate. By numerical simulation the quasi-phase matching conditions at different pump wave intensity are obtained. The dependence of layers lengths on pump wave intensity is computed. We received the models of media in which the Stokes-anti-Stokes amplification coefficient is higher than 10 dB.
