Internal conversion and strong-field molecular ionization with shaped few-cycle laser pulses

ORAL

Abstract

We study strong-field molecular ionization and internal conversion dynamics using few-cycle laser pulses tailored with an AOM based pulse shaper. The pulse shapes we used were chosen to illuminate internal conversion dynamics taking place during resonance enhanced strong-field molecular ionization. We measure the photoelectron spectrum as a function of pulse shape and use a recently developed model to interpret the pulse shape dependent molecular dynamics. Our results highlight the subtle interplay of electronic and nuclear dynamics involved in strong-field ionization.
