| 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方程发现，适当选取激光频率与跃迁的失谐量，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 Schrodinger equation shows that the population trapping can be removed by suitably detuning the laser frequency from the corresponding Bohr frequency. |

| Keywords: | resonant photon ionization laser isotopes separation population trapping. |
