We describe an all-pass fiber resonator with active phase-locking capability for accurate multiplication of the repetition rate of femtosecond light pulses. The cavity length of the resonator is precisely controlled using the Pounder-Drever-Hall phase-locking technique so that the repetition rate is multiplied in stabilization to the Rb atomic clock. Our test result proves the proposed phase-locking scheme is an effective means of generating higher repetition rate pulses with no significant power loss while providing a high degree of long-term stability.
我们描述了一种具有主动锁相能力的全通光纤谐振器，用于精确倍增飞秒光脉冲的重复频率。利用庞德 - 德雷弗 - 霍尔锁相技术精确控制谐振器的腔长，从而在与铷原子钟稳定同步的情况下倍增重复频率。我们的测试结果证明，所提出的锁相方案是一种有效的方法，能够在不产生显著功率损耗的情况下生成更高重复频率的脉冲，同时提供高度的长期稳定性。
