Photorefractive four-wave mixing with partially coherent light beams

We study here the four-wave mixing in photorefractive crystals with light beams of partial temporal coherence. We consider the evolution of the mutual coherence of the beams due to interaction and show how the partial coherence affects the efficiency of the phase conjugation process. In particular, we demonstrate that while initial low mutual coherence may be improved by wave mixing, it usually leads to a significant drop of the phase conjugate reflectivity.
