摘要： 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.
