A novel method for the exact solution of four-wave mixing in photorefractive media is
presented. This method allows us to treat exactly the effects of nonequal angles of …

A unified but simple method for solution of four-wave mixing equations in photorefractive
crystals in both transmission and reflection geometries is presented. The method is applied …

We obtain analytical solution to the slowly varying envelope wave equations describing two-
wave mixing in photorefractive crystals with arbitrary dependence of the gain and absorption …

We extend the standard model of four-wave mixing in photorefractive crystals to the case
where the Bragg-condition is broken by a slight departure from degeneracy. Our analytical …

Combined effects of cross and parallel coupling have been investigated in the case of
contradirectional two-wave mixing in an absorbing photorefractive crystal. Nonlinear …

We consider symmetries of two-wave mixing equations in photorefractive crystals, using
group theoretical methods. Symmetry groups for both the equations and conserved …

The effect of multiple internal reflections on the stationary energy transfer in degenerate two-
wave mixing, in a reflection geometry, with photorefractive crystals is studied. Numerical …

The effect of a position-dependent time constant on nondegenerate photorefractive two-
wave mixing is analyzed. For codirectional two-wave mixing the results indicate that the …

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 …
