一种新型的钠原子磁光陷阶（ＭＯＴ）磁光陷阱是冷却和捕获超冷原子的主要方法，目前国际上不少实验室中均已获得超冷原子气体。磁光陷阱的工作原理是在超高真空（１０７Ｐａ）钠原子吸收池中，用六束激光（上、下、左、右、前、后）交汇于吸收池中心。同时在吸收池上装有... A new type of sodium magneto-optical subsidence (MOT) magneto-optical trap is the main method to cool and trap supercooled atoms. At present, many laboratories in the world have obtained ultra-cold atomic gases. Magneto-optical traps work in the ultra-high vacuum (107 Pa) sodium atomic absorption cell with six laser beams (top, bottom, left, right, front and rear) that meet at the center of the cell. At the same time in the absorption pool equipped with ...
