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 0 6nm附近的高分辨率光谱
Using sideband frequency locking technology, dual-resonance OPO is stable single-phase operation in phase II semi-overall optical parametric oscillator (OPO). The OPO output can be continuously tunable and the maximum continuous tuning range can be achieved by tuning the pump optical frequency. 8GHz, which is applied to the frequency modulation spectrum of Cs2 molecule. High-resolution spectra of the Cs2 molecule near room temperature in the vicinity of 10 41.5 0 6 nm were observed
