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。
The corresponding relation between the absorption, dark state in degenerate two-levelFg=1→Fe=0 atomic quantum coherence between double A -type and single A -type the coherence based on the multi-ground state can be enhanced dispersion properties of probe field and system is studied, and comparation of system is discussed. The results show in the double A-type system.
