Photorefractive materials have been extensively used in recent years as real-time recording
media for optical holography.[1],[2] One prospective application of real-time holography is in …

The principle of incoherent-to-coherent conversion is demonstrated in several
photorefractive oxide crystals using a self-pumped phase-conjugator geometry. Resolution …

INTRODUCTION rials has produced new methods for self-pumped and mutual phase
conjugation and beam coupling. Spatiotemporal effects, such as transverse pattern …

The photorefractive effect first observed in LiNbO3, LiTaO3, BaTiO3, and KTN [1, 2] showed
that these materials underwent a change in index of refraction after illumination with low …

In many sensor protection applications, it is useful to selectively attenuate a strong coherent
beam in the presence of a collinear, weak white light image. We call a device which can …

This is the first of two volumes that review, for the first time, all major aspects of
photorefractive effects and their applications. Photorefractive effects in electro-optic crystals …

There is a growing demand for nonlinear optical materials for a variety of applications—
lasers and coherent sources, electrooptic devices, communication technologies, and optical …

Photoaddressed spatial light modulators (SLMs) or light valves generally employ a
longitudinal electro-optical effect, where the electro-optic voltage is controlled by a …
