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-step excitation with long laser pulses is presented. Based on a four-level model, the lifetimes are obtained by computer-aided analog between experimental results and theoretically calculated curves, and in agreement with those obtained by other methods.
