摘要

对亚多普勒二向色原子蒸汽激光锁定误差信号的解析建模表明，该误差信号的斜率可用于碱原子超精细光谱中跃迁的识别。在碱原子的四种D1谱线跃迁中，只有基态和激发态的land g因子均为负时，亚多普勒误差信号的斜率符号不同。所采用的分析模型包括所有亚能级跃迁，与实验光谱结果吻合得很好。这种技术的使用使我们能够准确地表征碱原子中的超精细跃迁，而不需要先进的光谱工具。

Sub-Doppler dichroism as a useful tool in alkali atom hyperfine spectroscopy

Abstract Analytical modeling of the sub-Doppler dichroic atomic vapor laser lock error signal shows that the slope of this error signal could be of interest for the identification of transitions in alkali atom hyperfine spectroscopy. Among four D1 line transitions of alkali atoms, the slope sign of the sub-Doppler error signal is different only for the case when the Landé g -factor is negative for both the ground and excited states. The analytical model used, which includes all sublevel transitions, shows very good agreement with the experimental spectroscopy results. The use of this technique allows us to accurately characterize hyperfine transitions in alkali atoms without the need for advanced spectroscopic tools.
