چکیده
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.

Plane-wave theory of nondegenerate oscillation in the linear photorefractive passive phase-conjugate mirror.
The observation of frequency-shifted phase-conjugate reflection in photorefractive passive (self-pumped) phase-conjugate mirrors1' 2 (PPCM's) has given rise to considerable efforts for its theoretical explanation. In this Letter we give a plane-wave theory of oscillation in the linear PPCM,3 compare it with the previously developed theory of detuning in the ring PPCM,2 and discuss the circumsta...

Optical bistable oscillation beams with a self-pumped phase-conjugate mirror are reported. The results of an experimental demonstration are given, and an explanation based on the threshold of oscillation is presented.
متن کاملCompression and broadening of phase-conjugate pulses in photorefractive self-pumped phase conjugators
Pulse propagation and shaping are investigated in photorefractive self-pumped phase conjugators in both transmissionand reflection-grating regimes. The dispersion properties of self-pumped phase conjugators are analyzed by taking into account both the grating dispersion and the angular dispersion. The complex transfer functions are obtained by treating the crystal as a linear dispersive medium....
متن کاملSpatio-temporal nature of the optical return field generated by four-wave mixing in photorefractive and Kerr materials
We have theoretically analyzed the return field produced by an externally pumped Kerr medium, an externally pumped photorefractive medium, and a self-pumped photorefractive medium, for an input field with arbitrary spatial and temporal characteristics. For a stationary beam with spatial structure, all three cases yield a spatial phase-conjugate return beam. For a beam with dynamic fluctuations,...
متن کاملTheory of self-frequency detuning of oscillations by wave mixing in photorefractive crystals.
Interesting experimental findings of self-frequencydetuning effects of phase-conjugate mirrors (PCM's) were reported recently. 1-3 A dye laser in conjunction with a passive (self-pumped) phase-conjugate mirror (PPCM) caused an unexplained self-frequency scanning of the laser.1' 2 Another system of a cavity formed by two PCM's also demonstrated a nondegenerate oscillation. 3 Recently4 we present...
