通过使用 Nd:YAG 激光泵浦 CsTiOAsO4 (CTA) OPO 的 1.8645-μ m 信号和 2.4793-μ m 闲频输出进行泵浦，研究了 CdSe 光学参量振荡器 (OPO) 的温度调谐。测量的温度相关相位匹配条件用于构建 CdSe 的新 Sellmeier 和热光色散公式，并通过在 10.2466、9.5525 和 9.2714 μm 运行的横向激发大气 (TEA) CO2 激光器的基波和二次谐波之间的温度调谐和频生成 (SFG) 进行验证。 (C)2022 Optica Publishing Group 根据 Optica 开放获取出版协议的条款
Temperature tuning of CdSe optical parametric oscillators (OPO's) is studied by pumping with the 1.8645-mu m signal and 2.4793-mu m idler outputs of a Nd:YAG laser-pumped CsTiOAsO4 (CTA) OPO. The measured temperature-dependent phase-matching conditions are used to construct new Sellmeier and thermo-optic dispersion formulas for CdSe, which are verified via temperature-tuned sum-frequency generation (SFG) between the fundamental and second harmonic of a transversely excited atmospheric (TEA) CO2 laser operating at 10.2466, 9.5525, and 9.2714 mu m.
