Abstract

We report a new two wave mixing interaction in photorefractive (P.R.) crystals Bi12SiO20 (B.S.O.) where the signal beam is time modulated at high frequency. It will be shown that the transmitted signal exhibits a differential gain γdiff at the same frequency and this even if the modulating frequency fm is much greater than the inverse of the material response time τ.
