摘要:采用含时多态展开方法,对不同频率啁啾激光场中里德堡锂原子布居数的相干迁移特性进行了计算研究.结果表明:布居数跃迁几率对激光脉冲形状、激光场强度、啁啾率等参数非常敏感,在合适的激光参数下,可以实现布居数在四个量子态之间的完全迁移和量子态的囚禁.
Using the time-dependent multilevel approach (TDML), we have calculated the coherent population transfer among the quantum states of lithium atom with different frequency-chirped laser pulses. The result shows that the population is very sensitive to the parameters of laser pulse, the population can be completely transferred to the target state and be trapped there by changing the parameters of the laser pulse.
