We present theoretical and experimental studies of the process of two-wave mixing of
broadband radiation in BaTiO_3. We show that the energy exchange in such a process can …

The kinetics of the phase conjugate beam generated by standard four-wave mixing in a
BaTiO3 crystal has been investigated by means of an accurate numerical simulation. The …

Two-beam coupling has been studied at red and near-infrared wavelengths in blue Rh:
BaTiO_3. High amplification, of the order of 20,000–37,000, of a weak signal beam has …

We report the operation of a two-wave mixing (TWM) photorefractive amplifier wherein
fanning of both pump and signal beams has been simultaneously suppressed to an …

A new scheme for high-efficiency phase conjugation of broadband laser radiation in
photorefractive crystals is proposed. The scheme utilizes a dispersive '2–f'system for …

We report two-wave mixing and self-pumped phase-conjugation measurements for GaAlAs
laser-diode radiation at 830 nm in BaTiO_3. At 11° C, two-wave mixing gain coefficients as …

Abstract. We demonstrate a new method of amplification and generation of light beams in
BaTiO [sub 3] by photorefractive forward four-wave mixing. The intensity of a signal beam is …

We report on the first observation of mirrorless oscillation in BaTiO 3 pumped by two nearly
counterpropagating mutually incoherent light waves, both containing an ordinary and an …

Relatively fast self-pumped phase-conjugate and four-wave-mixing rise times are reported
in n-type cobalt-doped barium titanate. With the crystal oriented in a 45° cut as compared …

We report the first observation to our knowledge of self-pumped phase conjugation in
BaTiO_3 at 1.06 μm. An essential feature is the lower threshold external ring configuration …
