摘要
对单光束通过蒸气薄池中的铯原子 6S1/ 2 → 6P3/ 2 跃迁的透射光谱进行了实验研究 ,其透射光谱呈现出亚多谱勒特性。利用频率调制技术提高信号的灵敏度 ,同时研究了激光强度对信号的影响。
The single light beam transmission spectrum of the 6S 1/2 →6P 3/2 in a thin (about 150 μm) vapor cell of the cesium atom is measured with freque n cy modulation technology. The high harmonics of the signal are measured correspo ndingly. The spectrum reveals sub-Doppler features. And the effect of the laser power on the signal is investigated.
