摘　　要：采用边带锁频技术 ,在II类相位匹配半整体光学参量振荡器 (OPO)中实现双谐振OPO稳定单频运转 ,通过调谐抽运光频实现OPO输出连续可调谐 ,最大连续调谐范围 2 .8GHz,将其应用于Cs2 分子的频率调制光谱 ,观测到室温附近Cs2 分子气室样品在 10 41.5 0Using the side-band frequency-locking technique, stable operation of cw OPO on single-frequency was achieved by type-Ⅱ semimonolitic KTP crystal. The output wavelength of the OPO is temperature tuned over a range of 5.8nm. The 2.8GHz continuous frequency tuning was achieved by tuning of the pump laser frequency, Furthermore, the application of OPO in frequency modulation spectroscopy of Cs was demonstrated around 1041.506nm.
