The evolution of polarization in holographically coupled beams traversing bismuth silicon
oxide (BSO) in the E?(1¯ 10) configuration is analyzed. The phenomena of electrical …

It is well known that light is able to modify properties of solid state media. Photorefractivity is
one of the brightest demonstrations of such an ability. The phenomenon is related to the …

This paper consists of two parts. The first contains a short review of the main characteristics
and holographic phenomena typical of sillenites, and the second part is devoted to new …

We consider the photorefractive response in a sillenite crystal with shallow traps when a
square-wave applied field is used. The numerical results give the dependences of two-beam …

We investigate numerically the dependence of higher harmonics of the space-charge field
on the detuning frequency between the pump waves, which form a running interference …

The principles of operation and the results of performance measurements are reported of a
new type of coherent optical receiver that used a dynamic volume index of refraction grating …

Theoretical and experimental investigations of the linear and nonlinear space–charge field
effects in photorefractive materials are reviewed. In particular, the aim is to explore the …

We show that Cu ions doped in (K x Na 1− x) 0.4 (Sr y Ba 1− y) 0.8 Nb 2 O 6 (KNSBN) form
two energy levels in the band gap, which increase the effective charge-combination-center …

This chapter provides the first systematic description of the basic properties of low-frequency
space-charge waves (SCWs) in photorefractive materials, and the effects caused by these …

The results of a theoretical analysis of the photorefractive response in crystals with shallow
traps to in a sign-alternating, square-wave electric field are presented. The numerical …
