Fig. 4: Tracking the evolution of light-induced molecular potentials in H2+ throughout a mid-IR laser pulse.
From: Probing multiphoton light-induced molecular potentials

a Vector potential of the mid-IR dressing field measured using the STIER technique. b–d Measured H+ momentum distributions in the polarization plane for different ionization times within the mid-IR pulse. The signal has been integrated over the delay ranges indicated by the brackets. The colorbar indicates the proton yield normalized to the maximum in each plot.
