Abstract
Using the so-called ac field technique, we investigate experimentally the influence of optical beam coupling on the generation of subharmoni c gratings in a photorefractive sillenite crystal. By the use of two d ifferent recording configurations, we are able to distinguish between effects caused by material nonlinearities and effects caused by optica l beam coupling.
