讨论了在强超短激光脉冲中中性分子电子基态相干振动波包的形成，以及通过最近发展的泵浦 - 探测实验对其进行的后续探测。波包的形成是由于强场电离速率对核间距有显著的依赖性。这导致由于与核间距相关的损耗，初始波函数发生变形。通过对氢分子进行含时波包研究展示了这一现象。
The formation of coherent vibrational wave packets in the electronic ground state of neutral molecules in intense ultrashort laser pulses and their subsequent detection by means of recently developed pump-probe experiments are discussed. The wave packet formation is due to the pronounced dependence of the strong-field ionization rate on the internuclear distance. This leads to a deformation of the initial wave function due to an internuclear-distance dependent depletion. The phenomenon is demonstrated with a time-dependent wave packet study for molecular hydrogen.
