- The theoretical models of sigle resonant OPO(SRO for short) and doubly resonant OPO(DRO for short) were established. In the base of the nonlinear coupling wave equations,the thresholds and the conversion efficiency curves of the two models were got. 建立了单谐振OPO(简称SRO)，双谐振OPO(简称DRO)理论模型，从非线性耦合波方程出发得到两种模型的振荡阂值以及转换效率曲线。
