摘要

采用辍饰原子模型研究了四光子三步共振离化过程的布居囚禁,发现了一种与离化速率无关的布居囚禁。通过数值求解裸原子表象的含时薛定谔(Shrodinger)方程发现,适当选取激光频率与原子跃迁的失谐量,可以解除这种布居囚禁。

Abstract

A process of four photon three step resonant ionization is investigated in terms of dressed atom model, and a kind of population trapping is found which is independent to the ionizing rate. Numerical calculation with time dependent Schrodinger equation shows that the population trapping can be removed by suitably detuning the laser frequency from the corresponding Bohr frequency.
