Amplified Scattering in a High Gain Photorefractive Polymer

A. Grunnet-Jepsen, C. L. Thompson, R. J. Twieg, and W. E. Moerner

We report the first observation of amplified scattering (beam fanning) in a photorefractive polymer. The manifestations of beam fanning and the implications for two-beam coupling measurements are investigated experimentally, and optimal geometries for observing or avoiding fanning are presented.
