This paper demonstrates the frequency-varied conjugation wave generation via nondegenerate four-wave mixing in photorefractive iron-doped lithium niobate crystal. The experiment uses 4880- and 6328-Å laser beams as mixing waves. The results are different from nearly degenerate four-wave mixing. The conjugation wave intensity depends on many parameters.
