Numerical Simulation of Self-Pumped Phase Conjugate Plane–Curve Loop Mirror Based on Photorefractive Nonlinearity

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.
