Abstract

We studied intensity of the Stokes component of the four-wave scattering by coherently excited phonon polaritons as a function of phase mismatches. Experiments in homogeneous LiIO₃, differently doped LiNbO₃:Mg, and periodically poled Nd:Mg:LiNbO₃ crystals are discussed from the scope of the conventional model. We found sufficient discrepancies between the model predictions and observed linewidths in LiNbO₃ crystals. The general expressions for the four-wave signal dependence from phase mismatches in periodically-poled crystals and in spatially-limited crystal areas are derived.
