Abstract :
We have studied the four wave mixing with partially coherent waves in photorefractive crystals with the transmission grating approximation both theoretically and numerically. The phase conjugation reflectivity depends much on the initial mutual coherence of the signal beam and the pump beam. The beam intensity and mutual coherence of the interacting waves are also obtained
