摘要：

A theoretical and experimental study of photorefractive nonlinear multi two-wave mixing is given. It is used to describe the fanning effect, which is an asymmetric self induced light scattering process, and is shown to originate from amplified noise. The cross section of the input beam is found to be very influential on the fanning strength. We also describe the bleaching mechanism of the fanning when a signal beam is added and amplified by two-beam coupling. © 1990.
