摘要
提出了一种测量原子高激发态能级寿命的简单方法，该方法采用与能级寿命同数量级的光脉冲二步激励样品，测量光电流信号与探针脉冲延时的关系，在四能级模型基础上，通过计算机模拟，求得结果，与其他方法所得结果一致。
A simple method to determine the lifetimes of excited saltes of atoms by two-stepexcitation with long laser pulses is presented. Based on a four-level model, the lifetimes areobtained by computer-aided analog between experimental results and theoretically calculatedcurves,and in agreement with those obtained by other methods.
