英文摘要: Quantum path control on the harmonic emission from a model Ne atom has been investigated within the scheme where a terahertz (THz) controlling pulse is added to a 5 fs/1200 nm fundamental chirp pulse. It has been found that, with the optimal THz field, the short quantum path has been selected and the super-continuum region of the harmonic spectra has been extended from 357 eV to 656 eV with less modulated structures. The proper superposition of harmonics without any phase compensation produces a single isolated 38 as attosecond pulse. (C) 2012 Elsevier B.V. All rights reserved.
