摘要
利用多普勒频移效应,通过线宽2MHz窄线宽激光与锶原子束在大角度作用下的荧光信号分析,测量了锶原子束速率分布。比较和分析表明,理论结果与实验结果符合较好。
Based on the Doppler frequency shift effect, the velocity distribution of strontium atomic beam is obtained by measuring the atomic fluorescence spectral induced by a laser beam at a large interaction angle. The comparison and analysis show that the experiment result conforms with the theoretical result fairly well.
