温度是影响晶体光折变性质的重要外界参数之一，目前人们已在多种晶体中对其温度依赖的光折变性质进行了研究．最近，我们在固定光栅间距下对掺铈和掺铑钛酸钡晶体的二波耦合强度及响应时间对温度的依赖性进行了研究．发现两种晶体的二波耦合强度随温度的上升而增加，同时响应
Temperature is one of the important external parameters that affect the photorefractive properties of crystals. At present, the temperature-dependent photorefractive properties of many kinds of crystals have been studied. Recently, we studied the dependence of the two-wave coupling strength and response time on the temperature of cerium-doped and rhodium-doped barium titanate crystals at a fixed grating spacing. It is found that the two-wave coupling intensity increases with the increase of temperature and responds simultaneously
