| 摘 要： | 本文理论计算了用圆锥管内多次全反射激光而产生的多普勒频移来冷却原子束的机制。给出了最佳冷却原子束的圆锥管的夹角、长度、反射次数及激光入、出射角等参数。理论计算了原子束经过圆锥管冷却的速度分布情况。数值计算结果表明：采用两个长１３０ｃｍ的锥形管来冷却原子束，选用合适的失谐量可使极大部分速度小于１２００ｍ／ｓ的原子冷却到８ｌｍ／ｓ，并且可得到单一速度的高亮度的原子束。

| Abstract: | A new method to cool atoms is proposed and discussed in theory.The parameters on this method are also given.The atomic beams slowed by repeatedly crossing a resonantlaser beam at a conical angle.The results show that not only almsost all the atoms below 1200m/s are cooled to 81 m/s,but also a high density monochromatic velocity atomic beam canbe obtained. |
