摘要
利用微扰理论,研究了具有一定延迟时间探测场作用下的梯型三能级系统.对激发态粒子布居分析的结果表明,随着延迟时间的变化,高位激发态的粒子布居以振荡形式出现,且振荡周期可以达到飞秒量级.
The population of excited state in ladder three-level-system which probe field has a delay(-time) between two pulses is studied by utilizing the perturbation theory. The analysis results show that population of the excited state becomes oscillating with the increase of the delay time and the oscillation period can reach femto-second order.
