本文报道了利用电磁感应透明（EIT）技术对锶原子激光束中里德伯态的全光探测。使用窄线宽CW激光器，我们得到了EIT线宽为5 MHz。为了说明这种方法提供的高光谱分辨率，我们已经测量了5s18d1D2和5s19s1S0里德堡态的同位素位移。这种技术可以应用于超冷里德伯气体和等离子体的高分辨率，非破坏性测量。
We report on the all-optical detection of Rydberg states in an effusive atomic beam of strontium atoms using electromagnetically induced transparency (EIT). Using narrow-linewidth CW lasers we obtain an EIT linewidth of 5 MHz. To illustrate the high spectroscopic resolution offered by this method, we have measured isotope shifts of the 5s18d1D2 and 5s19s1S0 Rydberg states. This technique could be applied to high-resolution, non-destructive measurements of ultra-cold Rydberg gases and plasmas.
