Abstract
We investigate the photorefractive phase conjugation in a Ce:Fe:LiNbO3 crystal as a function of temperature (293-393 K) and find the phase c onjugate reflectivity increases sharply in the vicinity of 55. 70 and 110 degrees C. The anomalous phenomenon is possibly concerned with the structural phase transformation of a crystal. which induces an extra internal electric held to influence the phase conjugation. The value o f the field is estimated at the order of 10(5) V/m, in agreement with the published data.
