| 英文摘要 | high-order harmonic generation from the molecular ion h-2(+) exposed to intense laser fields is investigated by the time-dependent quantum wave packet method. molecular and atomic plateaus of harmonic spectra are effectively distinguished at large internuclear distances, where the harmonic efficiency of the molecular plateau is several orders of magnitude higher than that of the latter. we report on a physical model of the origin of the molecular supercontinua and reveal that the creation of this plateau directly results from the interference of the intramolecular electronic wave packet localized in two potential wells following the laser field. this is our first effort in utilizing the efficient molecular plateau to generate intense isolated attosecond pulses by controlling the dynamics of the nucleus and electrons with a mid-infrared laser. further, we show that the harmonic plateau is enhanced at the macroscopic level by solving the maxwell wave equation coupled with the schrodinger equation. |
