Abstract

The numerical simulations of self-organization have been considered in the self-pumped phase conjugate compact loop mirrors based on a photorefractive crystal PRC BaTiO₃ . We show that under optimal condition the nonlinear reflection coefficient of such mirror achieves the maximum value 0.80 - 0.90 at the maximum conjugate fidelity equal to 0.95 - 0.98. In this geometry the conjugate wave-front is generated 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 is the same as self-pumped loop phase-conjugate-mirror (PCM) but substantially differs from a single-crystal double PCM.
