We describe our study of a phase-conjugate ring-resonator consisting of a Sagnac interferometer and a phase-conjugating mirror based on four-wave mixing in photorefractive BaTiO3. If the gain of the phase-conjugating mirror is higher than the losses in the passive part of the system, then the system exceeds the threshold, and without any externally incident signal the resonator shows the effect of self-oscillation. The spatial and temporal behavior of the self-oscillation pattern is investigated. We observe spatially chaotic behavior and a transition to regular behavior resulting from varying a control parameter. In spite of temporal fluctuations the spatially chaotic property is stable in time. The analysis indicates that the temporal behavior of the pattern is a regular behavior.
