英文摘要：

Continuum wavepacket interference is investigated by numerically solving the time-dependent SchrSdinger equation for the interaction of hydrogen atoms with laser fields. The obtained wavepacket evolution indicates that, in the over-the-barrier ionization regime （1016 W/cm2）, the continuum-continuum （CC） interference of ionizing electrons becomes the main process in high- order harmonics generation （HHG）, compared with continuum-bound （CB） transition, as reported by Kohler et al. [Phys. Rev. Lett. 105（20）, 203902 （2010）]. We propose a two-color laser field scheme for controlling the quantum trajectories of ionizing electrons and for extending the CC harmonic energy. As a result, a high energy platform occurs in the HHG spectrum, which entirely originates from the CC harmonics, with a cutoff adjustable by the relative phase of the two-color fields. This provides further understanding of the dynamic feature of atoms and molecules in super intense laser fields and provides an opportunity to image the atomic or molecular potential.
