摘　　要：首次报道四方相FeiKTN晶体的二波耦合性质.测得晶体的二波耦合增益系数和衍射效率分别为7.3cm^(-1)和42％,响应时间为2.8sec.文中还分析了主要载流子的符号并计算了其它参数.In this paper, the two-wave mixing properties of tetragonal phase Fe doped KTN crystal are repoted for the first time. A gain coefficient of 7.3cm-1 and diffraction efficiency of 42% were measured. The response time is 2.8 seconds. The Sign of the dominant oharge carriers is determined and some other parameters are calculated.
