The response of a photorefractive phase conjugator to time-varying signals is examined.
Maxwell's equations are coupled to the material equations followed by linearization using a …

Explicit expressions for the impulse-response function of a photorefractive phase conjugator
are derived. The expressions are in the form of an infinite series of Bessel functions. The …

We present wave-optics calculations of the temporal and spatial evolution from random
noise of a double phase-conjugate mirror in photorefractive media that show its image …

We investigate the mutually pumped phase-conjugation process in photorefractive media
with partially coherent pump beams. We consider the effects of transmission, reflection, and …

The development of a theory of four-wave mixing in photo-refractive crystals is described.
This theory is solved in the undepleted pumps approximation with linear absorption and …

We propose and analyze a new type of phase conjugation between counterpropagating
beams in photorefractive materials based on diffraction from transmission gratings only. This …

Stimulated photorefractive backscattering produces a phase-conjugate wave under some
conditions. Numerical solutions to the time-dependent wave equation for the backscattered …

In this letter we demonstrate and explain the lack of spatial information crosstalk between
beams in various oscillators by photorefractive CPR) wave mixing (WM). 1, 2 This study is …

We present two analytical methods of solving the coupled wave equations related to two-
wave mixing in a photorefractive medium in the case where the illuminating light pattern is …

A theoretical analysis is presented of two-wave mixing in photorefractive materials in which
the complex amplitude of a weak signal beam has slowly varying but otherwise arbitrary …
