摘要Using a linearly polarized, phase-stabilized 2.66-femtosecond driving pulse of 400nm central wavelength orthogonally combined with another linearly polarized long pulse of 800nm central wavelength irradiating jointly on the helium atom, we demonstrate theoretically the generation of a clean isolated 80-attosecond pulse in the spectral region of 93-155 electron volts in a two-dimensional model.
