以室温下的气室铯原子为介质,采用泵浦探测的方法获得激发态之间的光谱。在泵浦光与探测光相向、同向作用于铯原子得到的激发态超精细光谱有很大的差异。当考虑多普勒效应的影响,其分析结果与实验结果相一致。
The excited states spectra are obtained by pump-probe method in a room-temperature Cs vapor cell, which for both pump laser beam counter-propagating and co-propagating with probe laser beam schemes are very different. The experimental results are consistent with analysis results in consideration of the Doppler effect.
