Some possibilities of phase matching of Stokes components in stimulated Raman scattering

It is shown theoretically that the Stokes components can be phase-matched in dispersion-free media if the stimulated Raman scattering occurs in a resonator transparent at the pump frequency or if the signal is amplified. The frequency pulling effects and the stability of single-frequency stimulated emission of N Stokes components in high-Q resonators are discussed.
