利用受激拉曼绝热跃迁（STIRAP）技术，通过中间态22 s，实现了钾原子从22 p态到21 p里德堡态的跃迁。结果表明，完全布居转移与脉冲宽度和重叠度有关，当脉冲宽度和重叠度达到一定值时，完全布居转移发生。同时，也形成了人口陷阱。当满足双光子共振条件（Δs= Δp）时，也可以发生完全的布居转移。
The technique of stimulated Raman adiabatic passage (STIRAP) is used to transfer potassium atoms from the 22p state to the 21p Rydberg state through the intermediate state 22s. The results show that complete population transfer is related to pulse duration and overlap, and occurs when the pulse duration and overlap have adequate values. At the same time, population trapping is also formed. Complete population transfer can also occurs when the two-photon resonance condition (Δs= Δp) is met.
