论文摘要
我们演示了一种将连续波激光器的频率准确锁定到光学频率梳状态的方法，在信噪比较低的条件下，太低，无法容纳其他方法。我们的方法通常是比传统的波动器更准确的数量级，并且可以大大扩展给定光学频率梳的可用波长范围。我们通过将其应用于光学晶格时钟的偶极子晶格陷阱的频率控制中来说明我们的方法，这是一种代表性的情况，在这种情况下，我们的方法提供了比其他方法更高的精度。
We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb in conditions where the signal-to-noise ratio is low, too low to accommodate other methods. Our method is typically orders of magnitude more accurate than conventional wavemeters and can considerably extend the usable wavelength range of a given optical frequency comb. We illustrate our method by applying it to the frequency control of a dipole lattice trap for an optical lattice clock, a representative case where our method provides significantly better accuracy than other methods.
