Es bien sabido que una iluminación no-uniforme sobre un cristal fotorrefractivo provoca un
cambio espacialmente inhomogeneo de su birrefringencia. Esos cambios llevan a la …

Due to inherent complexity of some photorefractive effects, one must often resort to
numerical methods to describe them with some degree of realism. This is especially true …

The Doppler-enhanced self-diffraction configuration in photorefractive bismuth silicon oxide
crystals is used to perform incoherent-to-coherent optical conversion of two-dimensional …

When an image is observed through the photorefractive crystal, the multiwave mixing
between components of the image spatial spectrum should lead to drastic image distortion …

When the light inside the crystal has settled into a stationary pattern, lo and behold, the laser
beam is traveling back exactly along the way it came! The crystal acts as a mirror not an …

Photorefractive spatial light modulation based on Doppler-enhanced two-beam coupling in
bismuth silicon oxide crystals (Bi 12 SiO 20, or BSO) is demonstrated and analyzed. It Is …

The purpose of this study was to investigate the combined effects of optical activity and
linear birefringence on photorefractive crystals. The relation of input-output intensity was …

The aim of this work is to study and to optimize the diffraction efficiency in sillenite BTO
crystals. A theoretical analysis, where the effects of coupling beams are significant, is carried …

Doppler-enhanced self-diffraction in two-beam coupling experiments with sillenite crystals
exhibits pronounced optical polarization effects due to the concomitant presence of natural …

Beam propagation in nonlinear media, photorefractive crystals in particular, is an active field
of study. Most experiments are devoted to single-beam propagation. Another interesting …
