本文基于新型单波长外腔共振和频技术实现了转换效率高、波长可调谐589 nm激光的输出, 其中基频光波长分别为1583 nm和938 nm, 和频晶体为周期极化铌酸锂. 在1583 nm激光频率被锁定到外部环形腔腔模后, 通过对938 nm激光的频率扫描实现了输出功率4.96 mW, 调谐范围7 GHz的589 nm激光输出, 并采用声光调制器的伺服反馈技术有效提高了输出功率的稳定性. 最后采用该光源对钠原子在348—413 K (75—140 ℃)时D2线的饱和荧光谱进行了测量. 观察到了多普勒背景下钠D2a, D2b以及Crossover的亚多普勒结构, 其均可为589 nm频率的锁定提供参考信号.A wavelength-tunable laser output at 589 nm with high conversion efficiency based on sum-frequency generation by using the technique of single-wavelength extra-cavity resonance is achieved. The two fundamental wavelengths are 1583 nm and 938 nm and the nonlinear crystal is the period-poled lithium niobate. After the frequency of 1583 nm laser was locked to the cavity mode and the frequency of 938 nm laser was scanned, a 589 nm laser output with power of 4.96 mW and wavelength tuning range of 7 GHz was obtained and the stability of the output power is improved effectively with the help of servo feedback loop technique of acousto-optic-modulator. Finally, based on this laser, the saturated fluorescence spectrum of sodium D2 line in the temperature range of 348—413 K (75—140 ℃) were measured. The Doppler-free structures of D2a, D2b and crossover lines on Doppler background were observed, which can provide reference signals for the frequency locking of 589nm laser.
