The buildup and the decay of photorefractive two-beam coupling are experimentally
demonstrated to be strongly dependent on the intensity ratio of the two beams (signal-to …

The effect of partial spatiotemporal coherence in photorefractive two-beam coupling is
studied theoretically and experimentally. Coupled-wave equations and a beam-propagation …

A nonlinear theory of two-beam coupling is formulated using the decoupled Kukhtarev
equations in the steady state to account for arbitrary pump-to-signal intensity ratios. The …

In this paper, we present an analytic solution for high gain two beam coupling in
photorefractive crystals where one of the input beams may be time dependent. This is an …

A theoretical and experimental study of the temporal response of photorefractive two-and
four-wave mixing processes is given. We examine the buildup and the decay of the output …

We present and experimentally demonstrate a new method for enhancing the signal-to-
background ratio of two-wave mixing in photorefractive crystals. The method uses a mutually …

Photorefractive two-beam coupling with reduced spatiotemporal coherence is investigated
both theoretically and experimentally. Limited spatiotemporal coherence results in spatially …

The cross coupling of two mutually incoherent sources in photorefractive materials is
described. It is shown that when there are two mutually incoherent pump beams that are not …

The transfer function and impulse response of photorefractive two-beam coupling are
derived in the undepleted pump approximation. For sufficiently strong coupling Gamma L …

We investigate the dynamics of multiple two-wave mixing in photorefractive materials. This is
the first time to our knowledge that a study of the dynamics of many pairs of two-wave mixing …
