原子相干操控：基于EIT的原子时钟信号产生

In the experiment, we locked the 780nm laser to the transition frequency of 5S1/2 -> 5P3/2, and scanned the 480nm laser around the transition frequency of 5P3/2 -> X (X=76D5/2 or 78S1/2). The detection light and coupling light formed an EIT system. Based on this, we used a microwave signal generator to emit a microwave signal that satisfies the transition frequency of X (X=76D5/2 or 78S1/2) -> 79P3/2, causing the EIT transmission peak to split and form an ATS signal.
