介绍了一种基于Yb：环形光纤激光器的光学频率梳。据我们所知，这是第一次从振荡器直接产生f(CEO)，而不需要超过500 MHz重复频率的进一步放大。在300 kHz的分辨率带宽下，偏频的信噪比大于40d B，易于稳定。在没有温度控制的露天环境中，偏频稳定在6h以上。稳定的重复频率具有4.46×10(-13)/τ(1/2)的环路跟踪稳定性。
An optical frequency comb based on Yb:ring fiber laser was demonstrated. This is the first time, to our knowledge, f(ceo) has been generated directly from the oscillator without further amplifications above 500 MHz repetition rate. The signal-to-noise ratio of the offset frequency was above 40 dB at 300 kHz resolution bandwidth, which supports easy stabilization. The offset frequency was stabilized for more than 6 h in an open air environment without temperature control. The stabilized repetition rate has an in-loop tracking stability of 4.46×10(-13)/τ(1/2).
