title: Beam cleanup using photorefractive two-wave mixing.
abstract: Photorefractive two-wave mixing exhibits energy transfer without phase cross talk. Such a phenomenon can be used to clean up wave-front aberrations of laser beams. We report the cleanup of spatial and temporal phase aberration using photorefractive two-wave mixing in a strontium barium niobate crystal.
