| 摘 要： | 本文用含时多态展开方法研究了在两束部分重叠的脉冲场驱动下布居数在钾原子量子态中的相干迁移。结果表明，布居数能否实现完全迁移取决于两个脉冲的持续时间和重叠程度，当脉冲的持续时间和重叠合适时，将发生布居数的完全迁移，并形成布居数囚禁。

| Abstract: | By using the time-dependent multilevel approach, the coherent population transfer among the quantum states of potassium atom driven by partially overlapped pulse is studied. The result shows that the complete population transfer is related to both the pulse duration and the overlap, and takes place when the pulse duration and overlap each reach an adequate value, and at the same time population trapping is also formed. |

| Keywords: | stimulated Raman adiabatic passage coherent population transfer delay time |
