On sait, depuis l'avènement du laser, que l'intensité de la lumière est susceptible de modifier les propriétés optiques des matériaux. Cette optique « non linéaire » autorise l'interaction entre faisceaux lumineux par l'intermédiaire des mi

Rh are the only ones involved in the photorefractive effect at 1.06 μm. In this paper, we apply this model to the prediction of the steady-state photorefractive space-charge field. We present experimental measurements of induced absorption and beam-

We characterize Rh:BaTiO 3 by cw two-beam coupling experiments at 1.06 μm. We demonstrate that all our measurements are well described by a single-carrier, single-site model as soon as the incident intensity is large enough. The effective trap densi

On the basis of the Whole Beam Method, we describe the steady state photorefractive effect in optical devices where the crystal illumination is not a uniform interference pattern. The example of BSO, sitting in the Fourier plane of the two images of

The equations of the whole-beam method in photorefractive media have been derived and used to analyze the performances of a photorefractive correlator in the geometry of a joint transform correlator. Taken into account are the nonuniform, two-dimensi

Dramatic reduction of the number of oscillating modes in CW and pulsed lasers has been observed using a photorefractive crystal placed inside the cavity. Reflective Bragg gratings recorded by the standing waves inside the crystal act with the output
