Recently, experiments have been performed which demonstrate that interference between alternative excitation pathways in the laser excitation of atoms and molecules can be observed and controlled using non-linear conversion techniques. In order to obtain a better understanding of these phenomena, it is proposed to extend the work on measuring phase differences to (a) the effect of interfering processes on photo-electron angular distributions, (b) phase differences between the fundamental and third harmonic in third harmonic generations, (c) two-photon resonant cases and (d) control of relative production rates of excited states in atomic barium.

最近，已经进行了实验，其证明 大脑中不同的兴奋途径之间的干扰 可以观察到原子和分子的激光激发， 使用非线性转换技术控制。 为了 为了更好地理解这些现象，建议 为了将测量相位差的工作扩展到（a） 干涉过程对光电子角的影响 分布，（B）基波和 三次谐波产生中的三次谐波，（c）双光子 共振情况和（d）控制相对生产率 钡原子的激发态
