We present an experimental study of steady-state dark photorefractive screening solitons
trapped in a bulk strontium barium niobate crystal. We compare experimental measurements …

Current narrow-band optical filters for professional solar astronomy applications are
primarily based on Lyot filters. 1 However, the Lyot filter is severely limited in operation at UV …

The photorefractive effect [1] can loosely be defined as a light-induced change in the optical
properties of a material when the incident light is spatially nonuniform. The spatial …

The advances of photorefractive optics have demonstrated many useful and practical
applications, which include the development of photorefractive optic devices for computer …

We discuss the compromise between depth and transverse spatial resolution for
photorefractive holographic imaging through turbid media. Results from an optimized …

Stimulated photorefractive backscattering produces a phase-conjugate wave under some
conditions. Numerical solutions to the time-dependent wave equation for the backscattered …

We present experimental evidence demonstrating that the photorefractive-index change
responsible for the formation of photorefractive spatial screening solitons and coherent …

We demonstrate that recording thick holographic phase gratings in photorefractive polymers
can lead not only to very efficient Bragg diffraction but also to rather strong diffraction into …

The time evolution of space-charge field gratings in photorefractive media is derived for a
simple two-level electron–hole-transport model. At one level, charge transfer occurs by …

We have developed an approximate analytic expression of two wave mixing for absorption
and phase gratings in photorefractive materials taking into account self-diffraction effect of …
