Abstract

Two wave mixing (TWM) gain in photorefractive materials is one of the most fundamental and attractive aspects of the photorefractive effect. Several techniques for the enhancement of TWM gain have been developed and analysed by many researchers. In this paper we developed the corresponding theory describing the buildup of the space-charge field in the presence of square a.c. field and compared with the experimental results of the full temporal variation of the TWM gain for the square applied fields in a photorefractive Bi/sub 12/SiO/sub 20/ crystal. >
