Approach to space-charge field description in photorefractive crystals

Abstract

Recent analytical results in the frame of photorefractive spatial-soliton propagation are exploited to derive a novel scheme for the investigation of space-charge field formation in photorefractive crystals. The procedure is specialized to describe a two-wave mixing configuration. To test our predictions, we have performed an experiment in a sample of BaTiO_3.
