Abstract
We show that a hybridization of the optical and material nonlinearities tak es place near the threshold of the subharmonic generation in photorefractiv e crystals. It results in a critical (with a singularity) enhancement of th e rate of spatial amplification of light waves and leads to a variety of ne w optical critical phenomena.
