A new method for steering light beams with automatic (self‐aligning) Bragg matching is
presented. This device enables, in principle, a large beam deflection range which is not …

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 …

A two-dimensional model for the self-pumped phase conjugation in photorefractive crystals
is presented. Numerical simulations of the beam path for beam fanning and the self-pumped …

We investigate propagation of light beams in photorefractive media by direct numerical
simulation. The two dimensional model is based on solution of nonlinear material equations …

We analytically solve the steady-state coupling equations of photorefractive two-wave
mixing with a rapidly phase modulated signal for an arbitrary complex coupling constant …

We present an experimental realization of an almost non-invasive stabilization and
manipulation method of coexisting and unstable states of pattern forming systems. In a …

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 a new approach to measure the phase shift between the photorefractive grating
and the interference pattern in two-wave-mixing experiments. This approach is based on …

A hologram generally is formed in a photorefractive crystal by the interaction of the grating
formulation that is due to the space-charge field that grows from the beam interference …

An operator approach to two-beam coupling in photorefractive media for which each beam
is composed of information that varies in both space and time reduces the problem to a …
