Dependences of the resonance SRS efficiency on the pump radiation and medium scattering centers were theoretically analyzed. It was shown that this efficiency cannot be significant because the pump radiation and Stokes components were highly absorbed

We have developed a theory for a two-photon transition when the frequencies of the absorbed or emitted radiation are in resonance with transitions to the same intermediate level in the medium. We have determined the conditions under which such resona

A system of equations is constructed for the power of the Stokes components generated individually or simultaneously by a steady-state Raman laser. Examples of lasing in one, two, or three components are used to show that these equations can be used
