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 ...

Sign of the dominant charge carriers in photorefractive crystals determined by a phase-locked holographic technique
(2015-01-01)
This work presents a holographic method based on active feedback techniques for determining the sign of the dominant charge carriers in photorefractive materials. A two-step procedure is proposed: first off a stationary ...

Photorefractive two-wave mixing phase coupling measurement in a self-stabilized recording regime
(Iop Publishing Ltd, 2008-10-01)
The measurement of the phase coupling. between the two-wave mixed transmitted and diffracted beams behind a photorefractive material is directly obtained using a self-stabilized recording technique. These phase coupling ...

Optimization of the diffraction efficiency in photorefractive crystals
(Sociedad Española de Optica, 2017-05)
The aim of this work is to study and to optimize the diffraction efficiency in sillenite BTO crystals. A theoretical analysis, where the effects of coupling beams are significant,is carried on. In addition, non-mobile ...
