| 英文摘要 | in this paper, we study the issue of single quantum path control and its role in attosecond pulse generation. by carrying out the time-dependent schrodinger equation analysis for the harmonic emission from a single he atom irradiated by the two-color laser field, consisting of a short 800 fundamental chirped pulse and a subharmonic 800-2400 nm control pulse, we find that the most favorable condition for attosecond generation is at the fundamental chirp parameter beta = 4.55 together with the zero-phase 2000 nm control pulse, in which the single quantum path (short quantum path) is selected to contribute to the harmonic spectrum exhibiting an ultrabroad supercontinuum of a 337 ev bandwidth. finally, an isolated attosecond pulse as short as 39 as is thus generated directly.
