Probing dynamic information and spatial structure of Rydberg wave packets by harmonic spectra in a few-cycle laser pulse

摘要: We demonstrate that the dynamic information and spatial structure of a Rydberg wave packet formed by two neighboring states can be simultaneously probed harmonic spectra in few-cycle laser pulse, where is produced pump field. By controlling time delay pump-probe pulses, present periodic variation, which directly illustrates electron oscillation between states. Specifically, taking advantage variation efficiency dip spectrum, one detect characteristics initial packet.
