| 摘 要： | 新一代光纤飞秒光梳在精密测量和基础物理研究领域中有着广阔的前景，一种通过数字电荷泵锁相环和温控电路相结合的方法可以精密控制光纤飞秒光梳。在实验中，我们成功搭建了光纤飞秒光梳系统。光梳的重复频率为129MHz，初始频率大约为33MHz。我们通过自主研发的温控和数字电荷泵锁相环成功地把光纤飞秒光梳成功地锁定在了由Agilent PSG Analog Singal Generator提供的标准微波信号上，锁定时间至少长达1天。锁定后的重复频率的抖动标准差为0.78mHz，与基准源同一个数量级且很接近，锁定后的初始频率的抖动标准差可达8.98Hz。

| Abstract: | The fiber-based femtosecond optical frequency comb has great potential in the field of fundamental physics and precision measurement. We describe an experimental apparatus for precise control of the fiber-based femtosecond optical frequency comb. The system is combined with a digital charge-pump phase-locked loop (CPPLL) and a temperature stabilizer. We built the optical comb system of which the repetition frequency is and the carrier-envelope offset (CEO) frequency is about 33MHz. We locked the frequency comb with the standard signal provided by the Agilent PSG Analog Signal Generator. The locked state can be maintained over 1 day. The standard deviation of repletion frequency is 0.78mHz which is the same order of magnitude with reference, and the standard deviation of CEO frequency can be 8.98Hz. |
