本文讨论了用短脉冲激发原子低位态的电子到里德堡态的波包的产生和探测。为了观察波包的运动，我们分析了一个时间延迟的双光子实验，其中第一个激光脉冲产生一个波包，然后由第二个短脉冲探测。当脉冲间的时间延迟是经典轨道时间的倍数时，双光子跃迁几率出现峰值。发展了一种半经典的形式来描述波包的运动，并分析了时延双光子过程。
We discuss the generation and detection of wave packets of Rydberg states by exciting electrons from a low-lying atomic state with a short pulse to a Rydberg series. To observe the motion of the wave packet, we analyze a time-delayed two-photon experiment, where the first laser pulse generates a wave packet, which is then probed by a second short pulse. The two-photon transition probability shows peaks when the time delay between the pulses is a multiple of the classical orbit time. A semiclassical formalism is developed to describe the motion of the wave packet and to analyze the time-delayed two-photon process.
