摘要
采用含时多态展开方法,对频率啁啾的激光场中的里德堡钾原子的布居数相干迁移特性进行了计算研究.结果表明:在合适的激光参数下,可以实现布居数在两个量子态之间的完全迁移和量子态的囚禁.
Using the time-dependent multilevel approach (TDMA), we have calculated the coherent population transfer among the quantum states of potassium atom by a single frequency-chirped laser pulses. The result shows that the population can be transferred to a target state and be trapped there by changing the parameters of the laser pulse.
