Classical dynamics of ionization, dissociation, and harmonic generation ofa hydrogen molecular ion in intense laser fields: A collinear model - art.no. 053403

We use the classical trajectory method to study the dynamics of a hydrogen molecular ion interacting with intense laser fields employing a collinear m odel. We have calculated the probabilities of ionization and dissociation a s functions of time and obtained the photoelectron and the nuclear fragment ation 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 calculati ons.
