We show that the spatial coherence of a partially incoherent light beam can be greatly
enhanced through an energy-conserving interaction with an incoherent or a coherent dark …

This monograph collects together papers by leading researchers in the field of
photorefractive nonlinear optics. All of the works are presented by eminent researchers in …

We investigate contradirectional two-wave mixing with partially coherent waves in
photorefractive crystals in the nondepleted pump regime. Equations governing the …

We investigate contradirectional two-wave mixing with partially coherent waves in
photorefractive crystals. By use of a statistical theory on linear systems, a general …

A two-beam coupling interaction of an information-bearing beam with a copy of itself in a
photorefractive medium changes the spatiotemporal nature of the beam. We analyze the …

We study experimentally and theoretically temporal and spatial coherence of white light
beam through its interaction with a coherent dark spatial soliton in LiNbO3: Fe …

We present theoretical and experimental studies of the process of two-wave mixing of
broadband radiation in BaTiO_3. We show that the energy exchange in such a process can …

We discuss here the unidirectional photorefractive ring oscillator taking into account the
finite coherence time of the pumping light source. We exactly solve wave mixing equations …

We investigate the coupling of two partially coherent waves in high-speed photorefractive
media. When the coherence time of the optical waves is close to the speed of the …

We demonstrate a simple, adjustment-insensitive technique for measuring the temporal
coherence function of cw multimode and monomode semiconductor lasers, using two-beam …
