Abstract

We theoretically demonstrate the generation of extreme ultraviolet supercontinua in an orthogonally polarized two-color few-cycle laser field. We show that the ionized electrons can be driven back to their parent ion after traveling along curved trajectories in a plane perpendicular to the beam propagation direction, giving rise to a train of attosecond pulses at different polarization angles. A single isolated attosecond pulse can be obtained by blocking the low-order high harmonics, which contribute to the formation of the satellite pulses.

For comparison, 1D classical trajectory of the electron ionized at t4 in single color 9fs/1300nm laser field is shown in (e). Initial positions of the electrons are indicated by solid dots in all figures, and the motion directions of the recolliding electrons are indicted by arrows in (a–c).

(a). X- and Y- components of the high-order harmonic spectrum produced in orthogonal two-color field; (b) the corresponding phase profiles. Dashed curves: X-component; solid curves: Y-component; and (c) the intensity spectra of harmonics generated in two-color field (red), in single-color 800nm/9fs field (blue) and in single-color 1300nm/9fs field (black). The intensity of harmonics generated in two-color field is obtained by summing up the intensities of both the X- and Y-components of harmonics.

The corresponding pulse envelopes are shown in (d–f), respectively. The intensities of the attosecond pulses can be directly compared from the intensity values indicted on the Y-axes in (d–f).
