我们演示了从具有250 MHz脉冲重复率的锁模飞秒光纤激光器的光频梳（OFC）中选择单个梳线，并应用于Rb原子在1529 nm处的精密光谱学。采用光谱模式滤波和飞秒激光注入锁定技术，从模间距为1.5 GHz的光纤OFC中选择了单梳状线。当锁模飞秒光纤激光器的重复频率在250 MHz，382.6 Hz范围内扫描时，利用OFC的选择性梳状线在196，037，213.8 MHz，300 MHz范围内扫描，观察到Rb原子5S（1/2）-5P（3/2）-4D（3/2）跃迁的双共振光泵浦谱。
We demonstrated the selection of a single comb-line from an optical frequency comb (OFC) of a mode-locked femtosecond fiber laser with a 250 MHz pulse repetition rate, and applied for precision spectroscopy of Rb atoms at 1529 nm. The single comb-line was selected from the fiber-OFC with a 1.5 GHz mode-spacing using spectral-mode-filtering and femtosecond laser injection-locking. When the repetition rate of the mode-locked femtosecond fiber laser was scanned over the range of 382.6 Hz at 250 MHz, we observed the double-resonance optical pumping spectra of the 5S(1/2)-5P(3/2)-4D(3/2) transition of Rb atoms using the selected comb-line of an OFC scanned over the range of 300 MHz at 196,037,213.8 MHz.
