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. |
