  We demonstrate and characterize that a carrier-envelope-phase
(CEP)-controlled ultrashortchirped field is an efficient and robust mechanism
to modify the dissociation dynamics of molecularhydrogen. Different
dissociation pathways are collectively induced and their interference
contributeto the kinetic energy release spectra. Chirping is able to
efficiently manipulate the interferencesof different dissociation pathways. We
demonstrate a linear relationship between chirp and CEP-dependence,
dissociation as well as directional electron localization.
