Abstract
Three image processing experiments were performed by degenerate four-wave mixing in photorefractive GaAs. The experiments were imaging by phase conjugation, edge enhancement, and autocorrelation. The results show that undoped, semi-insulating, liquid-encapsulated Czochralski-grown GaAs crystals can be used as effective optical processing media despite their small electro-optic coefficient.Keywords
