Fragmentation of H2 + in 25 fs, 800 nm laser pulses and the intensity is 2.0 × 1014 W/cm2. ((a) and (b)) Calculated probabilities (N for residual probability of molecular ion, Diss for dissociation and CE for Coulomb explosion) for v = 3 state and v = 6 state, respectively. ((c) and (d)) The KER spectra for dissociation (dashed-dotted line) and CE (dashed line), and 1D results (black solid line) from Ref. 7 for v = 3 state and v = 6 state, respectively. The peaks 1 and 2 (red) for our calculation and the peaks 1, 2, and 3 (black) for 1D result.
Comparison of the temporal evolution of the electron probability density for v = 3 state by 3D simulation with that of by 1D calculation.
KER spectra for dissociation and ionization from v = 0 to v = 9 state.
(a) The total KER spectra for dissociation (red dashed-dotted line) and CE (green dotted line) by Franck-Condon averaging from the contributions of v = 0–9 states. The solid black line is from the 1D simulation.7 (b) The same as (a) but the parameters of the laser field is consistent with the experiment.36 The black solid line is the experiment result. The inset shows the detail of CE KER spectrum.
(a) KER spectra for 45 fs, 790 nm and 1.1 × 1014 W/cm2 laser field (red solid line for dissociation spectrum and green dashed line for CE spectrum). (b) The same as (a) but the laser is 135 fs, 790 nm, and the intensity is 1.0 × 1014 W/cm2.
