one-, two-, and three-beam optical chaos and self-organization effects in photorefractive materials

摘要

Collective selforganization effects and chaos are commonly observed in optics. We describe examples in a particular kind of nonlinear optical matterial: photore- fractive crystals. In particular, we show different effects that arise when photorefractive crystal s are illuminated one laser beam, two laser beams, and three laser beams.
