摘要
利用连续激光激发钠原子 ,在钠原子D1谱线的激发谱中发现了两个凹陷 .研究了相干驱动场激励下的三能级系统激发谱并进行计算和分析 ,给出了激发谱的变化规律 ,得到了与实验一致的结果 .实验与理论分析表明 。
An experiment is reported in a sodium vapor cell with cw laser pumping. Two dips in the excitation spectra of the sodium D 1 line are observed. Theoretical excitation spectra in the three_level system is calculated and analyzed in detail and the results are identical with experiments. It is demonstrated that the appearance of the two dips in the excitation spectra is closely related to quantum interference effect.
