Abstract： We present a method of measuring the parameters of a photorefractive crystal in codirectional two-wave mixing that is suitable for two-wave mixing in the intermediate stage (before saturation). Three parameters of a crystal. the exponential gain coefficient, saturation intensity and intensity absorption coefficient. can be measured simultaneously by using this method. The three parameters of a Ce:KNSBN are measured and the measured data are checked by another independent measurement.
