We report on the photoabsorption, magnetic circular dichroism (MCD) and electron
paramagnetic resonance (EPR) of Ge-doped CdTe. Strong photoinduced absorption …

By applying pulsed electric fields to photorefractive crystals, the two-wave mixing gain is
considerably increased. Unlike other enhancement techniques, the maximum gain is not …

Electroreflectance measurements are reported for bulk and epitaxial CdTe layers grown by
molecular‐beam epitaxy (MBE). Spectra are analyzed to determine the E 0, E 1, and E 1+ …

We study experimentally the photorefractive gratings decay in semi-insulating germanium
doped cadmium telluride crystals. The estimates for the diffusion length of free carriers LD …

We report an accurate mathematical model describing the photo-electromotive-force signal
produced by a speckle pattern of light vibrating in the volume of a photorefractive crystal with …

We present a novel way to determine the type of dominant carrier photoexcited from deep
traps in a photorefractive semiconductor. A numerical analysis of a picosecond free-carrier …

Modulation of built-in surface electric field was well established as a mechanism of
photoreflectance (PR) processes in bulklike semiconductors, though pump light induced …

We present an adaptive interferometer based on the reflection dynamic hologram recorded
in photorefractive CdTe: V crystal with no external electric field. Linear phase-to-intensity …

We report the beam-coupling properties of a cobalt-doped oxygen-reduced n-type barium
titanate crystal in the 0° and 45° crystallographic orientations. Oxygen reduction improved …

The intensity-dependent two-wave mixing gain at large modulation depth is measured in a
BaTiO3 crystal. We derive an expression of nonlinear space-charge field from Kukhtarev's …
