We present a real-time holographic interferometer for which two reference waves of different
phases are created by two-wave mixing with a stationary signal wave in a photorefractive …

In a photorefractive Bi 12 SiO 20 crystal with high applied electric ac field of square-wave
shape a fast two-wave coupling response (less than 1 s) and a slow hologram readout …

It is demonstrated that the emergence of subharmonics during two-wave mixing in a
Bi_12SiO_20 photorefractive crystal under applied alternating electric fields will markedly …

Illumination of a photorefractive crystal by light containing two interference patterns
(generally running) is considered. As well as linear terms in the response, the nonlinear …

We develop the theory of vectorial beam coupling in cubic photorefractive crystals to
describe the effect of fast phase modulation on output intensities and polarizations. Special …

We present a theory of resonant photorefractive wave coupling in cubic photorefractive
crystals that are in general optically active. This theory includes the resonance enhancement …

We theoretically study the characteristics of low-frequency space-charge waves in semi-
insulating GaAs: EL2 crystals. The calculations are based upon the literature data on the …

Four-wave mixing with cross-polarised pump beams is known to produce infinite phase
conjugate reflectivities at a coupling strength of ΓL= 4 in the undepleted pumps …

We present the first complete theoretical model that describes the formation of the space-
charge field in a photorefractive material that is exposed to a sinusoidal ac electric field with …
