Fig. 3: Verifying rolling and looping dynamics in a multicycle laser pulse.
a The simulated KER spectra as a function of the peak intensity of a ten-optical-cycle 400-nm laser pulse. b Populations of the 2pσu state after the laser-H2+ interaction, i.e., the proton yield, as a function of the laser intensity. The red curve is obtained by integrating the two-dimensional map in (a) over the whole KER region. The blue curve is numerically simulated by only switching on the dipole transition at Rω. The maxima of both curves are normalized to one for the convenience of comparison. c The dissociation yields as a function of the KER obtained by integrating the two-dimensional map in (a) within the laser intensity regions of [0, 1 × 1012], [5 × 1013, 9 × 1013] and [1.3 × 1014, 2 × 1014] W/cm2, corresponding to the 1st, 4th and 6th peaks, respectively. d Temporal evolution of the density distribution of χu calculated with the laser intensity I0 = 1 × 1014 W/cm2, labeled by the green dashed line in (a). The five small red arrows denote that the outward NWP undergoes five Rabi oscillations. The initial state in the calculation is the v = 6 vibration state
