我们开发了一种原子束横向压缩方案，该方案基于二维版本的磁光囚禁。即使对于多能级原子，该方案的可行性也可以通过将单能慢钠原子束的亮度提高三个数量级以上来证明。原子束从初始直径约3毫米压缩到最小直径43μm，密度超过109个冷原子/cm~3。研究了各种实验参数对最终束流大小的影响。
We developed a scheme for transverse compression of atomic beams, based on the two-dimensional version of the magneto-optical trap. The feasibility of the scheme even for a multilevel atom could be demonstrated by enhancing the brightness of a monoenergetic slow sodium atomic beam by more than three orders of magnitude. The atomic beam is compressed from an initial diameter of about 3 mm down to a minimum diameter of 43 μm, resulting in a density of more than 109cold atoms/cm3. The dependence of the final beam size on the various experimental parameters is investigated.
