A continuous compound four-wave mixing mechanism for self-pumped phase conjugation in photorefractive crystals is presented. The coupled-beam equations of this mechanism are solved numerically when depletion of the forward going beam is neglected. The experiment in a Ce-doped BaTiO<sub>3</sub> crystal is performed, with the stable phase conjugate reflectivity of as much as ≥ 80%. The curved high output phase conjugate intensity are explained using the numerical results.
