摘要：

The influence of a chirped laser pulse (5- fs, 800- nm) on dissociation and ionization processes for hydrogen molecular ions at low vibrational levels with different intensities has been discussed by numerically solving the one-dimensional time-dependent Schrodinger equation. By employing the "virtual detector" method, the probabilities and kinetic- energy- release spectra of dissociation and Coulomb explosion channels have been calculated. The results indicate that both the dissociation and ionization processes could be enhanced with proper chirp parameters; additionally, the dissociation process occurring at an early time in the chirped laser field is more sensitive to chirp parameters at low intensity due to the enhancement of the bond softening channel. The corresponding theoretical explanation is also provided.
