Analyzing anisotropic diffraction properties of photorefractive gratings in GaAs crystals and
the symmetry difference of energy exchange between index-of-refraction and amplitude …

Because of the light-induced bleaching of GaAs at λ= 1.064 µm, the amplitude gratings
strongly affect the photorefractive recording in this material. We extract two contributions that …

The polarization dependence of two-wave mixing for two common crystal orientations is
described and theoretical and experimental results given. The direction of energy exchange …

We report observation of a rotation in the polarization of the two photorefractive recording
beams in GaAs for a configuration with the internally generated space‐charge field along …

We present observations of polarization-flip photorefractive two-beam coupling in a GaAs
crystal, using both cw and pulsed Nd: YAG lasers. Here, two s-polarized waves are coupled …

A simple polarization technique for separate measurement of absorption and phase gratings
in photorefractive crystals, that allowed us to demonstrate experimental evidence of …

We demonstrate a novel way to analyse carrier recombination and transport processes in
photorefractive semiconductors via the exposure characteristics of light induced diffraction …

We have developed an approximate analytic expression of two wave mixing for absorption
and phase gratings in photorefractive materials taking into account self-diffraction effect of …
