| 摘 要： | 采用含时多态展开方法(TDML),对超高斯频率啁啾的激光场中的里德堡钾原子布居数相干迁移进行了计算研究,结果表明:在合适的激光参数下,采用超高斯啁啾脉冲可以实现布居数在量子态间的有效跃迁.通过对该体系动态Rabi频率的分析,得出:实现布居数囚禁的关键不在于具体Rabi频率的大小,而在于实现Rabi频率的适时跳转.

| Abstract: | The characteristic of population transfer of potassium atom by frequency-chirped super-gauss laser pulses is studied by using time-dependent multilevel approach(TDML).With the calculation of the population transfer of Rydberg potassium atoms with different super gauss index and half pulse width,the population is excited to the target states eventually.By studying the system's dynamic Rabi frequency,it has been found out that trapped population doesn't consist in the magnitude of the Rabi frequency,but in th... |
