Abstract

It is shown that the two-wave amplification in an alternating field in photorefractive crystals of the sillenite family is strongly affected by the drift length of photoinduced charge carriers. Consequently in samples with short drift lengths the two-wave amplification in an ac field is much less effective than that in a dc field.
