对腔内和频(SFG)单谐振光参量振荡器(IC-SFG-SRO)进行了理论计算，获得了323 nm的可调谐紫外光辐射。在平面波近似下，建立了考虑SRO和SFG过程不同空间有序性的简单模型。计算结果与实验结果吻合较好，并得到了一些重要的模拟参数。根据这些参数，预测和优化了532 nm绿光泵浦和1064 nm红外激光泵浦的532 nm绿光泵浦和1064 nm红外激光泵浦的SRO的输出特性。这些模型和仿真参数为连续波IC-SFG-SRO的优化提供了指导。
Theoretical calculations of a singly resonant optical parametric oscillator (SRO) with intracavity sum-frequency generation (SFG) (IC-SFG-SRO) are presented to obtain tunable ultraviolet laser radiation at 323 nm. Under the plane-wave approximation, simple models considering different spatial orderings of SRO and SFG processes are set up. The calculations are in good agreement with the experimental results, and some important simulation parameters are also obtained. According to these parameters, the output characteristics of the 532 nm green laser pumped SRO with an intracavity SFG between the pump and the resonant signal near 822 nm and the 1064 nm infrared laser pumped SRO with an intracavity SFG between the pump and the resonant signal near 1644 nm are predicted and optimized. The models and simulation parameters provide guidelines for optimizing the continuous-wave IC-SFG-SRO.
