| 英文摘要 | in this paper, we theoretically investigate the asymmetric molecular high-order harmonic emission and the attosecond x-ray pulse generation when the asymmetric molecular heh2+ ion is exposed to an intense chirped pulse. it is found that the molecular harmonics are strongly dependent on the internuclear distance r as well as the chirp parameter, showing a smooth and intense harmonic plateau at r = 8.0 a.u. and beta = 0.4. further, by adding a subharmonic controlling pulse with the optimised conditions, a supercontinuum with a bandwidth of 602ev can be obtained. finally, by properly superposing the selected harmonics in the supercontinuum region, a series of isolated x-ray pulses with durations of sub-80 as are directly generated. |
