论文摘要
在宇宙学，气象学和微波测量的广泛领域中，开发频率梳光谱技术具有潜在的应用和前景。在这里，我们通过多微波场敷料演示了Rydberg微波频率梳光谱仪，提供精确的微波测量。 Rydberg微波频率梳光谱提供了一个实时和绝对的频率测量，范围为125 MHz，并给出单频微波信号的相对相。报道的实验有助于使用Rydberg Atoms在宽范围内实时感知未知的微波信号，这对于基于Rydberg-Atom的微波计量学至关重要。
Developing frequency combs spectral technologies has potential applications and prospects in the wide fields of cosmology, meteorology, and microwave measurement. Here, we demonstrate a Rydberg microwave frequency comb spectrometer via multiple-microwave field dressing, providing precise microwave measurement. The Rydberg microwave frequency comb spectrum provides a real-time and absolute frequency measurement with a range of 125 MHz and gives the relative phase of a single-frequency microwave signal. The reported experiment helps real-time sensing of an unknown microwave signal in a wide range using Rydberg atoms, which are vital for Rydberg-atom-based microwave metrology.
