摘　　要：对 3～ 5 μm角度调谐 Li Nb O3 光参量振荡器给出了完整的理论设计过程 ,用动量和能量守恒分别计算给出了角度调谐曲线、有效非线性系数和参量增益曲线 ,确定了光参量振荡器的相位匹配方式和晶体的切割角 ;根据参量光输出变化范围计算了晶体的接收角和光波走离角 。For 3~5μm angle tuned LiNbO 3 optical parametric oscillator,an integrated theoretical design process was presented.Based on conservation of energy and momentum respectively calculation of angle tuned curve,effective nonlinear coefficient curve and parametric gain curve were set forth.Phase matching angle of the OPO and cut angle of the crystal were determined.Crystal acceptance angle and light wave walkoff angle were calculated on the basis of the varying range of output parametric light and the experimental accuracy of the OPO was determined.
