We present the development of a holographic interferometer based on a dynamic hologram
recording with photorefractive crystals of the sillenite family and which is adapted for the …

We present an alternative procedure to determine the effective electro-optic coefficient (reff)
and the electric screening field factor by measuring the optical intensity variation induced by …

A digital feedback control loop system is used to produce high-efficiency photorefractive
gratings in reflection geometry for volume narrow band reflection filters. The system allowed …

The chapter reviews recent progress of two-wave mixing in a novel organic-inorganic hybrid
structures that combine essential properties as large anisotropy and strong birefringence …

The measurement of the phase coupling φ between the two-wave mixed transmitted and
diffracted beams behind a photorefractive material is directly obtained using a self-stabilized …

We report on the light-induced absorption in undoped photorefractive Bi_2TeO_5 (BTeO)
crystal. The so-called “two-center” model is shown to adequately describe the present …

We report the use of Lloyd's mirror interferometer for holographic recording in
photorefractive material. The experimental results show that perturbations in the diffraction …

The lifetime of the excited charge carriers in Cr-doped Bi12TiO20 (BTO) crystals is
characterized by measuring the optical density changes after nanosecond pulse excitation. It …

A high quality fixed holographic grating was recorded in a photorefractive LiNbO_3: Fe
crystal at about 100° C in a homemade temperature-controlled vacuum chamber. The …
