摘要
文章分析了简并二能级原子系统Fg=1→Fe=0中的吸收、色散特性与暗态的对应关系,比较了双Λ型和Λ型能级结构下的量子相干效应。结果表明, 双Λ型系统中多个基态相干性会增强原子相干特性。
Abstract
The corresponding relation between the absorption, dispersion properties of probe field and the dark state in degenerate two-level Fg=1→Fe=0 atomic system is studied, and comparation of the quantum coherence between double Λ-type and single Λ-type system is discussed. The results show that the coherence based on the multi-ground state can be enhanced, in the double Λ-type system.
