A finite difference method is used to analyze the behavior of photorefractive InP: Fe at high
fringe contrast under externally apphed field. The evolution with increasing fringe contrast m …

Photorefractive recording response to sinusoidal intensity pattern in photovoltaic media
under different boundary conditions, namely, open-circuit, crystal-resistor-circuit, short-circuit …

We apply directly a perturbative expansion to the hopping model of Feinberg. The first three
harmonics of the space‐charge field are presented, considering the contributions from the …

An analytical solution of the dynamic coupled wave equations as a function of time in a
photorefractive medium at large modulation depths is presented by using the empirically …

For Gaussian-beam-induced optical limiting based on photoconductive field shielding of
electro-optic (EO) birefringence, power-limiting notch widths may be accurately determined …

The optimum performance of a photorefractive two-beam coupling fluence limiter is
presented. A two-level, singie-dopant-species model is used to determine the minimum …

A theory for dynamic holographic processes in photorefractive crystals in transmission
geometry is presented as well as a numeric solution of the problem by the simulation …

La souplesse d'emploi des matériaux photoréfractifs est un de leurs principaux attraits. Un
même échantillon est sensible sur une plage de longueurs d'onde de plus de 100 nm avec …

In dieser Arbeit wurden photorefraktive Kristalle mit dem Rasterkraft mikroskop detailliert
untersucht. Dabei konnten erstmals lichtinduzierte Ladungsgitter in den Kristallen mit hoher …

Spatio-temporal pattern formation in contra-directional two-wave mixing in photorefractive
crystals is investigated both numerically and analytically, taking high-modulation-depth …
