Ionization of the H2+ by intense ultrashort laser pulses

The ionization of H2+ by intense ultrashort electric pulses is theoretically studied using quantum mechanical and classical approaches. In the quantum mechanical treatment the numerical solution of the time dependent Schroedinger equation (TDSE) is considered along with the Volkov and momentum-space strong-field models (MSSFA). Classical calculations were performed in the framework of the classical trajectory Monte Carlo (CTMC) method. The influence of the two-center Coulomb potential on the interference effects before, during and after the ionization process is analyzed in details.
