All-optical control of impulse parameters is realized via a dynamical transmission four-wave

We investigate spatio-temporal dynamics of two-wave mixing processes in a photorefractive

We show that the standard model of four-wave mixing in a photorefractive crystal predicts
the appearance of deterministic chaos. In this model there is a single (transmission) grating …

The phase part of the system of equations describing two-wave mixing in a photorefractive

The steady-state coupled wave equations for four-wave mixing (FWM) in a cubic, non-
optically-active photorefractive crystal are solved for the case of orthogonally polarized …

The basic phenomena of transverse dynamics of a two-wave mixing photorefractive
oscillator (PRO) in the weakly multimode case are considered. The evolution of the …

We present the analytical solution of the coupled equations system that describes two-wave
mixing (2WM) in photorefractive media as an adaptive beam combiner. The crystal operates …
