论文摘要
我们提出了一种新的方案，使用两个不同的时钟激光器询问温暖的rubidium蒸气。从性能角度来看，这种方法与最近提出的两彩两光子rubidium时钟有明显不同，因为我们的方案无法权衡AC Stark抑制，而不是对细胞温度/压力的敏感性提高。取而代之的是，我们的方法弥补了全部，AC-Stark的移位以及温度和压力诱导的频移。所提出的方案还利用了调制转移技术，这使信噪比的数量级增加了两个数量级，而依赖荧光测量的传统时钟。
We propose a new scheme for interrogating a warm rubidium vapor using two different clock lasers. Performance-wise, this approach is distinctly different from the recently proposed two-color two-photon rubidium clocks as our scheme does not trade off the AC Stark suppression against an increased sensitivity to the cell-temperature/pressure. Instead, our approach compensates all, the AC-Stark shift and the temperature & pressure-induced frequency shifts. The proposed scheme also makes use of the modulation transfer technique, which enables a two-orders of magnitude increase in the signal-to-noise ratio compared to traditional clocks that rely on fluorescence measurements.
