We propose a method to obtain higher phase-conjugate reflectivity by using a pulsed pump beam as the reading beam. A qualitative explanation of our method is given. Then we calculate the transient phase-conjugate reflectivity, considering that the reading beam erases the grating in a photorefractive crystal. The reflectivity when a continuous reading beam is used is compared with that when the pulsed beam is used. We prove experimentally that approximately three times greater reflectivity can be obtained with a pulsed reading beam.
