Thermo-optics parameters measurements in photorefractive sillenite Bi(12)SiO(20) crystals by thermal lens technique
(NATL INST OPTOELECTRONICS, 2011)
The present work reports on the thermo-optical properties of photorefractive sillenite Bi(12)SiO(20) (BSO) crystals obtained by applying the Thermal Lens Spectrometry technique (TLS). This crystals presents one high ...

The effect of bulk light absorption on running photorefractive holograms
(Iop Publishing Ltd, 2000-01-01)
The influence of bulk light absorption on running photorefractive holograms is investigated. By solving the coupled wave equations we prove that the beam intensities, but not the beam phases, can be calculated by averaging ...

Feedback-controlled running holograms in strongly absorbing photorefractive materials
(2000-09-01)
We propose a mathematical model for the movement in absorbing materials of photorefractive holograms under feedback constraints. We use this model to analyze the speed of a fringe-locked running hologram in photorefractive ...

Effects of the induced birefringence in photorefractive crystals on speckle optical vortices
(Elsevier, 2012-03)
In this work, we show that it is possible to change the properties of an optical vortex formed in a speckle pattern by the control of an external electric field applied to a sillenite-type photorefractive material in a ...
Oscillating holograms recorded in photorefractive crystals by a frequency detuned feedback loop
(American Institute of Physics (AIP), 2009-01-15)
We report an optoelectronic feedback loop suitable for generating noise-free interference patterns oscillating at arbitrary waveforms. The technique allows controlling the frequency detuning between the interfering beams ...
