论文摘要
我们介绍使用二维磁光陷阱创建锂 - 沿慢光束的创建。两种原子梁被指示以在超高真空中加载三维磁磁带。我们达到的负载率为1.3 $ \ times $ 10 $^{7} $锂原子/S，锂烤箱温度为370〜 $^{\ circ} $ c和2.2 $ \ times $ 10 $^{7} $ cesium cesium cesium cesium cesium/s，cs oven温度为20〜 $^{\ circ} $ c。陷阱中锂原子的最大数量分别为1.0 $ \ times $ 10 $^{9} $和1.4 $ \ times $ 10 $^{8} $。我们的结果表明，简单而紧凑的二维磁光陷阱适合生产具有较大质量比和非常不同的挥发性的两个物种的原子束。
We present the creation of a lithium-cesium slow beam using a two-dimensional magneto-optical trap. The two-species atomic beam is directed to load a three-dimensional magneto-optical trap in ultrahigh vacuum. We achieve a loading rate of 1.3$\times$10$^{7}$ lithium atoms/s with the lithium oven temperature at 370~$^{\circ}$C and 2.2$\times$10$^{7}$ cesium atoms/s with the Cs oven temperature at 20~$^{\circ}$C. The maximum numbers of lithium and cesium atoms in the trap are 1.0$\times$10$^{9}$ and 1.4$\times$10$^{8}$, respectively. Our results show that the simple and compact two-dimensional magneto-optical trap is suitable for producing an atomic beam of two species that have a large mass ratio and very different volatilities.
