论文摘要
数据学生可以从典型的高级本科实验室中收集到rubidium的饱和吸收光谱（SAS）的典型高级本科实验室，可用于测量同位素移位，从而导致同位素基态能量转移的估计值。这有助于学生完善原子基础状态的“图片”。我们从理论上描述了为什么该实验室在自由运行的激光二极管中很好地工作，并使用这些激光器调整为主要的近红外过渡，并使用调制传递光谱法显示了实验室的实验表明。
Data students collect from the typical advanced undergraduate laboratory on Saturated Absorption Spectroscopy (SAS) of rubidium can be used to measure the isotope shift and thus leads to an estimate of the isotopic ground state energy shift. This helps students refine their `picture' of the atomic ground state. We describe theoretically why this laboratory works well with free-running laser diodes, demonstrate it experimentally using these lasers tuned to either principal near-infrared transitions, and show an extension of the laboratory using the modulation transfer spectroscopy method.
