Paper 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.
