We report the nonresonant excitation of the nonstationary holographic currents in an
external sinusoidal electric field. The theoretical analysis of the effect has been performed …

We report the simultaneous combined excitation of the space charge and photoconductivity
gratings in photorefractive Bi 12 Si O 20 and Bi 12 Ti O 20 crystals. The experiments are …

A nonlinear interaction of moving space-charge and photoconductivity gratings is
experimentally investigated. In the presence of a dc electric field, a crystal is irradiated with …

We modified the theory of the holographic current, describing both the steady-state and the
transient contributions and accounting for the parameters of the measurement circuit. In the …

We report resonant excitation of space-charge and photoconductivity waves in
semiconductors with shallow energy levels. We predict the appearance of several …

It is shown that the two-wave amplification in an alternating field in photorefractive crystals of
the sillenite family is strongly affected by the drift length of photoinduced charge carriers …

Starting from the three-dimensional version of a standard photorefractive model (STPM), we
obtain a reduced compact set of equations for an electric field based on the assumption of a …

We report a mathematical formulation that successfully describes the holographic
photocurrent that is produced, in strongly absorbing photorefractive materials, by the action …

A new phenomenon associated with a nonlinear interaction of optically excited space
charge waves has been discovered in photorefractive crystals of the sillenite family. This …
