| 英文摘要 | in this paper, we theoretically investigate the delay time effect on the high-order harmonic generation (hhg) when a model ne atom is exposed to a two-color time delayed pulse, consisting of a 5fs/800 nm fundamental field and a 20fs/2000 nm controlling field. it shows that the hhg spectra are strongly sensitive to the delay time between the two laser fields, in particular, for the zero carrier-envelope phase (cep) phi case (corresponding to the 800 nm fundamental field), the maximum cutoff energy has been achieved at zero delay time. however, with the introduction of the cep (phi = 180), the delay effect on hhg is changed, exhibiting a 'u' structure harmonic emission from -1t to 1 t. in addition, the combinations of different controlling pulse frequencies and pulse intensities have also been considered, showing the similar results as the original controlling field case, but with some characteristics. finally, by properly superposing the optimal harmonic spectrum, an isolated 45as pulse is generated without phase compensation.
