Photorefractive Materials presents an overview of the basic features and properties of
photorefractive materials, covering a wide array of related topics. It provides a coherent …

We report two-beam coupling experiments at 1.06-μm wavelength using photorefractive
semi-insulating GaAs: Cr in the moving-grating recording mode. The steady-state gain …

Solutions to the band-transport equations are developed to include effects on the amplitude,
dynamics, and spatial-frequency response of the space-charge field when periodic or dc …

At wavelengths close to the band edge, strong photorefractive gratings using the Franz–
Keldysh electrorefractive effect can be written in semiconductors. Two‐beam‐coupling …

We have used a 20-kHz ac square-wave electric field to enhance the beam-coupling gain
and the degenerate four-wave mixing reflectivity of photorefractive GaAs at 1.06 μm. The …

The dependence of a two-beam coupling gain on the grating period in Fe-doped InP is
characterized. I measure gains as large as 4 cm^− 1 at 1.06 μm for an applied field of 8 kV …

We report a theoretical model for a photorefractive running hologram in bulk-absorbing
materials in the presence of self-diffraction and use this model to analyze experiments for …

The fundamental component of the space-charge field in a photorefractive crystal is studied
in the presence of an applied alternating electric field. A general equation for the amplitude …

It is shown that the two-wave amplification in an alternating field in photorefractive crystals of
the sillenite family is strongly affected by the drift length of photoinduced charge carriers …
