Abstract We deal with computer simulation of a transient process in a self-pumped phase conjugate plane--curve loop mirror based on BaTiO3. In optimal circumstances the nonlinear reflectivity and fidelity of such a mirror respectively achieve 0.80--0.90 and 0.95--0.98. The generation of conjugate wave-front occurs due to scattering from the dynamic hologram which is produced in the region of self-intersection of forward and backward beams. In such a model the scenario of passing to unstable generation regimes is similar to the self-pumped phase conjugate plane--plane loop mirror and substantially differs from a single-crystal double phase conjugate mirror.
