Abstract

A general expression for the photorefractive gain under step like electric field is derived. It shows the gain dependence on the applied field frequency which is confirmed experimentally. We show how optimum gain enhancement is achieved by adjusting the illumination and the field frequency to the characteristic times of the crystal. Simultaneous contribution of holes and electrons is also considered to explain reduced values of the gain observed in some cases.
