ABSTRACT:
The invention relates to a low-noise amplification device of an optical wave. Signal wave (F.sub.s) to be amplified interferes with a pump wave (F.sub.p) in such a nonlinear medium (1) as a photorefractive crystal. To reduce the noise considerably, even to eliminate it, the establishing of noise-generating interferences therefore is prevented by moving, by rotation around an axis O, the nonlinear medium.
