Critical enhancement of photorefractive beam coupling

By Podivilov, E.V.; Sturman, B.I.; Pedersen, H.C.1; Johansen, P.M.1

From

Risø National Laboratory for Sustainable Energy, Technical University of Denmark1

We show that a hybridization of the optical and material nonlinearities takes place near the threshold of the subharmonic generation in photorefractive crystals. It results in a critical (with a singularity) enhancement of the rate of spatial amplification of light waves and leads to a variety of new optical critical phenomena.
