我们展示了在强场分子电离过程中，利用整形、少周期的激光脉冲对内部转换进行相干控制。控制是由不同中性态的干涉驱动的，这些中性态通过分子哈密顿量中的非Born-Oppenheimer项耦合。我们的测量突出了在电子态之间的非绝热跃迁中电子相干性的保持。
We demonstrate coherent control over internal conversion during strong-field molecular ionization with shaped, few-cycle laser pulses. The control is driven by interference in different neutral states, which are coupled via non-Born-Oppenheimer terms in the molecular Hamiltonian. Our measurements highlight the preservation of electronic coherence in nonadiabatic transitions between electronic states.
