摘　　要：用单载流子一能级带导模型对ＢａＴｉＯ＿３晶体在８３０μｍ处双光束耦合的指数增益系数和响应时间温度特性的实验结果做了理论分析。在考虑了量子效率的温度特征后，理论能半定量地解释实验现象。The experiment results of the temperature dependence of the gain coeffi-cient and response time in two-beam coupling in BaTiO_3 crystal at 830nm are analyzed theoretically by using the one-carrier and One-level band-conduction model.The experi-mental phenomena could be explained semiquantitatively by using the theory after the temperature dependence of quantum efficiency is considered.
