摘要：
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 x 10(7) lithium atoms/s with the lithium oven temperature at 370 degrees C and 2.2 x 10 7 cesium atoms/s with the Cs oven temperature at 20 degrees C. The maximum numbers of lithium and cesium atoms in the trap are 1.0 x 10(9) and 1.4 x 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.
