… non-linear optics which exploit some of the unique features of the photorefractive effect. The
… that it can be used to amplify time-dependent signals) 32) Coherent image subtraction and …

… In this paper, novel applications of photorefractive effect, in the fields of optical signal
processing which so far have not been explored, are proposed and demonstrated. First, …

… laser systems and optoelectronic signal transmission and processing. The class of nonlinear
phenomena based on the photorefractive effects in electro-optic crystals will undoubtly play …

… modulated signals [ 4,201. We want to measure a signal Ed(O, t) which is phase modulated,
on a time scale very short compared to the response time of the photorefractive effect TV We …

… We report a novel technique for detection of the ultrasound-modulated optical signals by
use of the two-wave mixing process in a photorefractive crystal (PRC). PRC-based …

… photorefractive effect is now firmly established as one of the highest-sensitivity nonlinear
optical effects, … that distinguishes the photorefractive effect from other common nonlinear optical …

… -optic in origin, we recorded gratings at large applied voltage, removed the writing beams,
and observed the diA'racted signal … The Auctuations in the signal as it rises to its steady-state …

… the photorefractive effect, we first consider the photocurrents in both the absence and
presence of external electric fields in electro-optic crystals, including bulk photovoltaic effects but …

… The photorefractive effect is defined as the optical modulation … The interference of two laser
beams in a photorefractive material … as phase-conjugate mirrors and optical signal amplifiers. …

… The orientational mobility of the chromophores presents special problems, because both the
birefringent and the electro-optical effects contribute to the observed signals. This appendix …
