We present numerical simulations of the complex grating structure that is generated when
several longitudinal modes from a laser induce a self-pumped phase conjugator in a …

This thesis deals with new techniques for improvement of the coherence properties of high-
power laser diode arrays. A new configuration where a laser diode array is coupled to an …

Experimental results show that the wavelength selectivity and the shape of the detuning
curve of the complex grating structure formed in a photorefractive self-pumped BaTiO 3 …

A self-pumped forward phase-conjugate mirror based on nonlinear wave mixing in
photorefractive media is demonstrated. A single input beam to a BaTiO_3 crystal excites an …

Optical low coherence reflectometry is applied to measure with pm precision the type,
position and length of gratings inside a barium-titanate crystal producing self-pumped phase …

A numerical method to simulate the photorefractive phase conjugation process in rather
general conditions, pump depletion and multigrating operation, has been developed …

Transient high diffraction efficiency of phase-conjugate output in a photorefractive crystal of
BaTiO3 was measured for the case in which the reading beam illuminates the transmission …

We studied the evolution of patterns of scattered light in a barium titanate crystal, during the
process of self-pumped phase conjugation in a system with no external beam-reflecting …

A two‐dimensional model for the self‐pumped phase conjugation in a photorefractive crystal
is presented. In the model, no internal reflections at a corner of the crystal are explicitly …
