Abstract:
We analyze the effect of parametric coupling of different frequency components on the stimulated Raman scattering threshold depending on the four-wave mixing phase mismatch and material dispersion. A fundamental difference is observed in the way parametric processes affect the generation of Stokes and anti-Stokes waves. We show that as a result of parametric coupling of Stokes components, their generation thresholds strongly decrease and come closer to each other because they originate from an intense parametric rather than a spontaneous seed radiation. The theoretical analysis refines and extends the commonly accepted concept of stimulated Raman scattering in nonlinear crystals and demonstrates good agreement with new experimental data.
