Abstract

We describe semi-self-pumped photorefractive phase-conjugate mirrors based on the unidirectional ring resonator and the double phase-conjugate mirror. Their applicability to thresholding phase conjugation and one-way imaging through distortions is discussed.

The double PCM may be interpreted as a semi-self-pumped phase conjugator. When barium titanate is used, the crystal is tilted so that the c axis is neither parallel nor perpendicular to the bisectors of the beams. This enables extraordinarily polarized beams to use the high electro-optic coefficient r42.

(a) Original realization of phase-conjugate window with externally supplied pump. Beam A2 carries the picture information T. Probe beam A4 passes through distortion D, which must be imaged onto the crystal by lens L1. The reflected beam A3 carries the information through the distortion, is split off at beam splitter S, and is imaged onto the film by lens L2. (b) Semi-self-pumped phase conjugator applied in realization of the self-pumped phase-conjugate window. The experimental results of Fig. 6 were obtained with a barium titanate crystal pumped at 514.5 nm by a single-longitudinal-mode argon laser. The transparency-information-bearing beam was frequency shifted 40 MHz by an acousto-optic modulator to prevent the buildup of reflection gratings in the photorefractive crystal.
