It is shown by numerical simulations that the nonlinear refraction coefficient of a loop phase-conjugate (PC) mirror based on a BaTiO{sub 3} photorefractive crystal achieves under optimal conditions the maximum value 0.80-0.90 at the maximum overlap integral equal to 0.90-0.95. The conjugate wave is generated in such a mirror due to scattering from a dynamic hologram produced in the self-intersection region of the forward and backward beams. As a result, the scenario of passing to unstable generation regimes in this case substantially differs from that described earlier for a single-crystal double PC mirror.
