Abstract

We review the conditions of efficient interactions at 1.06µm wavelength with photorefractive GaAs. These interactions are based on the recording of moving interference patterns in the volume of the crystal (drift recording mode with an externally applied electric field) This technique results in large values of the exponential gain coefficient Γ ~ 6-7 cm -1 for an optimized grating velocity and grating spacing. Applications to image amplification, amplified four wave-mixing (R = 5) and self-induced optical oscillations are presented.
