| Abstract: | In this paper,a theoretical model for the influence of the temprature on space charge field inphotorefractive barium titanate and other crystals is proposed. The theoretical curve of E-T and r-Tare given. The curves show that the space charge field and the gain c0upling coefficient of two-wavemixing in BaTiO, are increased with increasing temperature. |
