An expression for the gain in photorefractive two-wave mixing when radio-frequency (rf)
electric fields are applied to the material has been derived and compared with experiments …

We present and experimentally demonstrate a new method for enhancing the signal-to-
background ratio of two-wave mixing in photorefractive crystals. The method uses a mutually …

This chapter provides a detailed review of theoretical work on the photorefractive effect. The
physical model of photorefractivity used here, which now seems well established by many …

A method of enhancing the degenerate four-wave mixing (DFWM) conjugate reflectivity in
photorefractive BSO is described, which uses an auxiliary beam of different wavelength to …

The fundamental component of the space-charge field in a photorefractive crystal is studied
in the presence of an applied alternating electric field. A general equation for the amplitude …

We demonstrate that two-wave mixing of partially coherent light beams inside a medium with
an inertial nonlinear response allows one to increase the coherence substantially. An …

The recent study of nonlinear optical properties of photorefractive materials has led to the
experimental observation of anisotropic energy transfer in two-wave mixing, l the …

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 …

High performance spatial light modulators (SLMs) are essential in many optical information
processing and computing applications for converting incoherent images to coherent …
