Optical Bistability by Two-Wave Mixing in Photorefractive Crystals

摘要

Optical bistability in photorefractive strontium barium niobate in a two-wave mixing configuration with feedback is reported. We observe bistability both under conditions for which its existence was recently predicted by Zozulya et al. (Opt. Commun. 72, 381 (1989)) and under more general conditions....Optical bistability, Two-wave mixing, Photorefractive crystals.
