We describe the experimental measurement of phase-conjugate reflectivity versus various
ratios of input-beam intensities in photorefractive barium titanate and strontium barium …

Two specially cut KNbO3: Fe crystals were used to study the self-pumped phase conjugation
with external and internal ring cavities. The design and operation of these conjugators are …

The influence of crystal-shape parameters on formation of self-pumped phase conjugation is
studied experimentally. The parallelism of two c-cut faces of a barium strontium potassium …

Obtaining self-pumped phase conjugation in photorefractive crystals without the use of
external mirrors usually requires that the crystals exhibit significant beam fanning and have …
