磁光阱目前已经成为量子光学领域内的一种强有力的研究工具。在实现了铯磁光阱后，我们通过对实验系统的改进提高了磁光阱的性能，在此基础上对磁光阱中原子数目和密度与磁光阱参数（包括激光光强、失谐以及磁场梯度等）的关系进行了系统的实验研究，结果与我们的理论预计［１］大致符合。同时我们还观察到在调节冷却激光光束准直和补偿地磁场的亥姆霍兹线圈电流过程中出现的冷原子云形状的变化，包括原子云的干涉图样、多亮点原子云、环形原子云、蝴蝶状原子云等，其中不少现象未见报道，对这些现象进行了初步分析。
Magneto-optical traps have now become a powerful research tool in the field of quantum optics. After the realization of the cesium magneto-optical trap, we improved the performance of the magneto-optical trap by improving the experimental system. Based on this, we analyzed the relationship between the number and density of atoms in the magneto-optical trap and the parameters of the magneto-optical trap (including laser intensity, And the magnetic field gradient, etc.) of the system of experimental studies, the results with our theory is expected to [1] roughly consistent. At the same time, we also observed the changes of the shape of the cold atomic cloud during the process of adjusting the laser beam collimation and compensating the Helmholtz coil current of the geomagnetic field, including the interference pattern of the atomic cloud, the bright spot atomic cloud, the annular atomic cloud, Butterfly-shaped atomic clouds, many of which have not been reported, a preliminary analysis of these phenomena.
