Classical dynamics of ionization, dissociation, and harmonic generation of a hydrogen molecular ion in intense laser fields: A collinear model

We use the classical trajectory method to study the dynamics of a hydrogen molecular ion interacting with intense laser fields employing a collinear model. We have calculated the probabilities of ionization and dissociation as functions of time and obtained the photoelectron and the nuclear fragmentation kinetic energy distribution spectra for various laser parameters. We have included a preliminary calculation of the harmonic generation spectra of a hydrogen molecular ion. In many cases, the classical results reproduce the qualitative features of the corresponding quantum-mechanical calculations.
