摘要:

报道了一种高效、紧凑的基于逆反射二维磁光阱(2D MOT)的高通量铯原子束源。我们通过在超高真空中将二维MOT准直器倾斜到一个单独的三维磁光阱(3D MOT)来实现一个有效的推动场分量。该技术显著地将3D MOT加载速率提高到大于$8 \times 10^9$原子/秒,对于源仅使用20 mW的总激光功率。当在饱和以下操作时,我们实现了$6.2 \times 10^{11}$ atoms/s/W的最大效率。

英文摘要:

We report on an efficient and compact high-flux Cs atom beam source based on a retro-reflected two-dimensional magneto-optical trap (2D MOT). We realize an effective pushing field component by tilting the 2D MOT collimators towards a separate three-dimensional magneto-optical trap (3D MOT) in ultra-high vacuum. This technique significantly improved 3D MOT loading rates to greater than $8 \times 10^9$ atoms/s using only 20 mW of total laser power for the source. When operating below saturation, we achieve a maximum efficiency of $6.2 \times 10^{11}$ atoms/s/W.
