摘要
Non-perturbative, time-dependent calculations are presented to study the photodissociation of H2+ in intense laser fields with the use of chirped pulse. The proton kinetic-energy spectra (PKES) was analyzed to study the kinetic-energy distribution structure of a proton due to intrapulse pump-dump mechanism between two electronic states for positive and negative chirping. The results showed the dynamics of an ion trap during dissociation process and suggested that the released proton kinetic energy depend o the speed of the intensity decrease.
