摘要

我们已经成功地在(1,1,1)原子喷泉几何形状中冷却和发射铯原子，温度低至0.8 /spl mu/K。这相当于0.7厘米/秒的均方根热速度，是光子反冲速度0.35厘米/秒的两倍。详细介绍了限制最终温度的因素。

Laser cooling and launching performance in a (1,1,1)-geometry atomic fountain

We have successfully cooled and launched cesium atoms in the (1,1,1) atomic fountain geometry at temperatures as low as 0.8 /spl mu/K. This corresponds to a root-mean-square thermal velocity of 0.7 cm/s, which is two times the photon recoil velocity of 0.35 cm/s. Factors that limit the final temperature are presented in detail.
