我们利用二极管激光的反传播辐射来冷却和阻止铯原子束。激光的频率被调整以保持与减速原子的共振。同样的激光被用来探测得到的速度分布。我们已经将每秒超过1010个原子冷却到1k的温度。这是一种极其简单和廉价的方法来控制原子速度，并有广泛的应用前景。
We have used counterpropagating radiation from a diode laser to cool and stop a beam of cesium atoms. The laser frequency was chirped to keep it in resonance with the slowing atoms. The same laser was used to probe the resulting velocity distributions. We have cooled more than 1010 atoms/sec to a temperature of 1 K. This is an extremely simple and inexpensive way to manipulate atomic velocities and has a wide range of possible applications.
