Abstract
The process of optical energy transfer via photorefractive two-beam coupling has been utilized by numerous investigators in a variety of applications of practical interest including optical interconnection and computing, image processing, and laser hardening. In such optical systems involving a photorefractive amplifier, accurately predicting the speed at which the amplifier will respond becomes a necessary facet of system design. As a result, the temporal response of the photorefractive effect has been the subject of extensive investigation. However, these investigations have not yet resulted in an explicit expression for the response time in the presence of beam coupling as a function of the various relevant material and environmental parameters. While such an expression is presented in this paper, substantial progress toward this result has been made previously by other workers.
