Recording of localized transmission gratings by four-wave mixing in non-local
photorefractive media with strong response is considered. The input conditions to record …

The physical origin of frequency shift and dynamic instability in a photorefractive self-
pumped phase conjugator is analyzed by use of four-wave mixing and multi-four-wave …

The mutually pumped phase conjugator with+ c-face incident geometry is first demonstrated
in a photorefractive pentagon-shaped 0°-cut BaTiO 3 crystal. Designed by choosing the …

Instead of unstable solutions for conventional four-wave mixing equation set, we obtain the
stationary soliton solution for the dynamic grating amplitude and stable auto-oscillations of …

By externally applying an electric field across a photorefractive BaTiO3 crystal we
experimentally demonstrate that the self-pumped phase conjugator in thecat'configuration …

We consider director configurations of cholesteric liquid crystal (CLC) cells with two plane
confining substrates. Exact solutions of the Euler-Lagrange equations for out-of-plane …

Experimental results are reported on temporal instability of phase conjugate beam in a self-
pumped Ce: BaTiO 3 phase conjugator at 532nm. The transition from stable output to …
