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 …

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

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 …

2.5 Conclusions Dynamic gratings can be induced by interfering laser beams in almost any
optical material. Some selected works related to laser-induced gratings have been used as …

Two-wave mixing measurements made during the encoding of plasma gratings in AlGaAs:
Te indicate that there is no phase shift between the illumination intensity pattern and the …

The diffraction properties of fixed volume gratings, including the effect of additional
photorefractive energy coupling between the incident wave and the diffracted wave, are …

We examine simultaneous write–read of dynamic photorefractive gratings for arbitrary phase
shifts between index grating and intensity pattern. The nonlinear behavior of diffraction …

Two-wave mixing gain in photorefractive GaAs: Cr using the moving grating technique has
been measured. The results compare well to theory when a value of τ di/τ 2 measured by …

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 consider the diffraction properties of index gratings in photorefractive media, assuming
an arbitrary momentum mismatch (Bragg mismatch). The incident and diffracted waves …
