Dynamic Bragg gratings can be recorded in rare-earth (eg Er, Yb) doped optical fibres by
two counter-propagating mutually coherent laser waves via local saturation of the fibre …

Light-induced charge transport processes are essential for photorefractive effects in
electrooptic crystals. Charge driving forces, charge transport models and experimental …

We report the observation of nonlinear photorefraction in pure aligned nematic liquid
crystals in the presence of an applied dc electric field. The effect is attributed to nematic axis …

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 …

In liquid crystal cells with photoconductive poly (Nv inlylcarbazole⁠) polymer layers, an
external dc field can be completely screened by surface charge layers that develop at the …

We demonstrate an improved laser-based receiver for the detection of small ultrasonic
surface displacements. The receiver is based on a homodyne interferometer using a …

We describe the self-stabilized holographic recording in Fe-doped LiNbO3 crystals reaching
almost 100% diffraction efficiency using weak interfering beams of 514.5 nm wavelength …

We derive an analytical expression describing the effect of phase modulation in two-wave
mixing for dynamically recorded phase-shifted holograms in photorefractive materials. The …

We report measurements of the photorefractive phase shift and coupling constant of several
photorefractive materials. We solve the problem of beam coupling and diffraction in a …

A small photochromic grating is selectively and continuously detected from a much larger
photorefractive modulation in Fe-doped LiNbO3 crystals in a two-wave mixing experiment …
