论文摘要
使用极薄的蒸气细胞允许的光谱分辨率增加，导致观察到碱性转变的有趣行为。特别是，遵守明显的$ f_e-f_g \equivδf= \ pm2 $选择规则（称为磁引起的（MI）过渡，其概率大大增加，而中等相互作用方案的概率大大增加，而在零处为零和更高的磁场。将800 nm厚的CS蒸气电池放置在最高1.5 kg的田地中，我们在这里表明，电磁诱导的透明度（EIT）的产生，以$λ$ - 系统的涉及$ΔF= -2 $ 2 $ 2 $ MI的过渡才有可能在$λ$ - 系统中，只有在coupling tarmiate和探针范围内才有可能，$ nimriend是$ $ $ $ nimartival tallivation-$ $σ^^^quartiald-$σ^^ - - - - 二分性能。可以以$ΔF=+2 $ mi转换和$σ^+$极化的$ΔF=+2 $ MI的转换。由于频率较高的斜率（典型4 MHz/g），涉及MI转变的EIT共振的产生很有趣，尤其是在日益注意到对微型碱蒸气细胞传感器的关注的情况下。
The increased spectral resolution allowed by the use of extremely thin vapor cells has led to the observation of interesting behaviour of alkali transitions when placed in a magnetic field. Particularly, transitions obeying an apparent $F_e-F_g\equivΔF =\pm2$ selection rule, referred to as magnetically-induced (MI) transitions, have their probabilities largely increase in the intermediate interaction regime while being null at zero and higher magnetic fields. With an 800 nm-thick Cs vapor cell placed in a field up to 1.5 kG, we show here that the generation of electromagnetically induced transparency (EIT), realized in $Λ$-systems involving $ΔF =- 2$ MI transitions, is only possible when both the coupling and probe beams are $σ^-$-circular polarized, demonstrating that EIT is affected by magnetic circular dichroism. A similar rule of thumb can be extrapolated for $ΔF =+2$ MI transitions and $σ^+$ polarization. Because of the high frequency shift slope (typ. 4 MHz/G), the generation of EIT resonances involving MI transitions is interesting, especially in the context of growing attention towards micro-machined alkali vapor cell sensors.
