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.
