Influence of alternating field frequency on enhanced photorefractive gain in two-beam coupling

Abstract

We derive an analytic expression describing the intensity and field frequency dependence of photorefractive gain in two-beam coupling under an alternating square-wave electric field. We determine the frequency and intensity ranges over which the gain is maximum and time independent. Experimental results for Bi12GeO20 crystals are presented.
