Photoconduction and hologram recording in a Bi 12 SiO 20 single crystal are studied from
both theoretical and experimental points of view in the case of short pulse excitations. An …

A numerical simulation of the photorefractive grating dynamics using high intensity pulses of
nanosecond length and under an external electric field has been made. The band transport …

The dynamic behaviour of both diffracted beams in a two-wave mixing configuration, and
induced photocurrent are investigated with nanosecond light excitation. The 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 …

We have developed a time-of-flight technique for measuring the mobility of photoexcited
charge carriers in certain crystals exhibiting the electro-optic effect. We used this …

We report on the nonlinear relation between the resonance hologram velocity and the
recording light irradiance in fringe-locked running hologram experiments carried out on a …

We report nonstationary photorefractive holograms in absorbing Bi_12TiO_20 samples with
different degrees of hole-electron competition exhibiting resonance peaks due to electron …

This is the first characterization of both positive and negative charge carriers as well as deep
traps in any crystal sufficient to predict photorefractive behavior for all beam geometries on …

We have measured the real and imaginary parts of the experimental rate constant of the
buildup and decay of photorefractive charge gratings in cubic crystalline insulating Bi 12 SiO …
