The photodetachment of the ##IMG## [http://ej.iop.org/images/0953-4075/53/18/185102/baba203ieqn20.gif] {${\text{H}}_{2}^{-}$} ion in a time-dependent electric field is investigated for the first time. On the basis of time-dependent closed orbit theory, we calculate the photodetachment cross section (PCS) of a ##IMG## [http://ej.iop.org/images/0953-4075/53/18/185102/baba203ieqn21.gif] {${\text{H}}_{2}^{-}$} ion manipulated by a Gaussian laser field. We use the superposition principle and consider the interaction between two atomic centers in the ##IMG## [http://ej.iop.org/images/0953-4075/53/18/185102/baba203ieqn22.gif] {${\text{H}}_{2}^{-}$} ion to construct the electron wave function after photodetachment from the ##IMG## [http://ej.iop.org/images/0953-4075/53/18/185102/baba203ieqn23.gif] {${\text{H}}_{2}^{-}$} ion. Three different types of closed orbits for the photodetached electron in the...
