We have investigated experimentally and theoretically the mixed Raman-parametric generation of Stokes components under biharmonic pumping. We show that in the presence of a strong pump component the power of the weak component, which is needed for the observation of the stimulated Raman scattering, can be decreased by a factor of 104. The observed effect can be explained on the basis of phase locking in four-wave interaction.
