We report large enhancement of the two-beam-coupling gain in vanadium-doped cadmium
telluride. We used the applied-alternating-field method with square and sinusoidal …

The ac field technique leading to the enhancement of the photorefractive effect is applied to
vanadium-doped cadmium telluride. Net photorefractive gain is obtained for the three …

We have for the first time demonstrated two‐beam coupling energy transfer at a wavelength
of 1.5 μm. Beam coupling gain coefficients of 0.6 cm− 1 have been obtained in vanadium …

We present two-wave mixing results obtained with CdTe: V photorefractive crystals under an
external dc or low-frequency square-shaped periodic electric field. The majority …

The first study of the photorefractive properties of doped CdTe has demonstrated high
sensitivity for optical processing applications. Of the binary II‐VI and III‐V semiconductors …

Charge redistribution between two different photorefractive centers in CdTe: Ge allows for
enhancement of two-beam coupling at 1.064 µm and 1.32 µm by the additional illumination …

We present a photorefractive investigation of the vanadium doped CdTe at different
wavelengths from 1.06 μm to 1.55 μm. The sensitivity and performances of different samples …

The photorefractive properties of two CdTe: V crystals are compared in the infrared range.
For both crystals, an increase of the electron-hole competition factor (from electrons to holes) …

We report on the observation of a photorefractive effect with picosecond pulses in a material
that has little or no midgap absorption (less than 0.1 cm− 1). We model our data using rate …

We present electro-optical characterization (by deep level transient spectroscopy, deep level
optical spectroscopy and photo-induced current transient spectroscopy) on vanadium doped …
