Abstract  A continuous compound four-wave mixing mechanism for sell-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 BaTiO3 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.
