多光子跃迁中饱和现象的一种理论解释

An Explanation of Saturation Phenomenon in Multiphoton Transition

采用一种新的理论方法计算了一维量子体系的多光子跃迁几率，结果表明， 这种新的理论方法能够给出多光子跃迁中饱和现象的主要特征。

The multiphoton transition probability of an one-dimensional quantum system is calculated by using a new method. The results show that firstly, the present method is in agreement with the traditional perturbation method for lasers with low intensity, but the practical calculations based on the former are much simpler than on the latter; secondly, the present method can produce the essential features of saturation phenomenon appeared in the case of high intensity lasers.
