K-型五能级原子的双重单光子电磁诱导透明

Double Electromagnetically Induced Single-photon Transparency in a Five-level K-scheme Atomic System

当一个Ξ-型三能级原子的中间态分别被两个控制光场耦合到另一个激发态和基态时,该原子的两个抽运光场所对应的吸收谱出现双重单光子透明.该吸收谱的性质与两个控制光场Rabi频率和基态非辐射衰变率有关.

When the intermediate level in a three-level -scheme atom is coupled to an excited and a ground levels by two control fields, respectively, the atomic system exhibits the phenomenon of double electromagnetically induced single-photon transparency. The absorption spectra are related to the Rabi frequencies of the two control fields and the non-radiative decay rate.
