Abstract

We theoretically investigate the generation of high harmonics and attosecond pulses by mid-infrared (IR) driving fields. Conditions for coherent build-up of high harmonics are revisited. We show that the coherence length dictated by ionization-induced dephasing does not constitute an ultimate limitation to the coherent growth of soft X-ray (> 100 eV) harmonics driven by few-cycle mid-IR driving pulses: perfect phase-matching, similar to non-adiabatic self-phase-matching, can be achieved even without non-linear deformation of the driving pulse. Our trajectory-based analysis of phase-matching reveals several important advantages of using longer laser wavelengths: conversion efficiency can be improved by orders of magnitude, phase-matched build-up of harmonics can be achieved in a jet with a high gas pressure, and isolated attosecond pulses can be extracted from plateau harmonics.

Contributions from different half-cycles of a 2-cycle laser pulse (inset in panel a) to high harmonics at 400 eV. For λ L = 0.75μm, a rapid increase of the harmonic signal (panel a) often coincides with a peak of the single-atom dipole response (panel b, solid lines). For λ L = 2.1μm (panels c and d), the observed highly efficient harmonic generation is due to phase-matching. In both simulations, the cut-off energy was equal to 700 eV at the beginning of propagation; cut-off energies of individual half-cycles are represented by dashed curves in panels b and d. Harmonic intensity in panels a and c is measured in the same units, propagation was simulated for a 100-mbar He jet starting from the focus of the laser beam. The dashed green line in panel c represents contribution from half-cycle 2 calculated with a non-divergent laser beam. In this case the harmonic generation is not phase-matched and a regular coherent ringing is observed.

Single-atom dipole response at the beginning of a 100-mbar He jet (a), and the far-field spectral intensity of high harmonics (b) generated by a 1-mJ 2-cycle pulse for different values of the laser wavelength λ L. In each simulation, the initial semi-classical cut-off energy was equal to 700 eV and the jet thickness L was chosen to reduce it by 10% (legend in panel b).

Fig. 3.

Generation of a single attosecond pulse in the plateau region. Panel a shows the far-field on-axis harmonic signal generated with λ L = 1.5μm (green dashed line in Fig. 2b) after it was transmitted through a filter made of 0.1 μm of Cu and 0.1 μm of Pd. The filter suppresses harmonics below 100 eV, its transmittance is shown by the inset in panel a. Panel b shows the time-domain intensity of the harmonic field after the filter.

Fig. 4.
Fig. 4.

Scaling of harmonic output with gas pressure p for λ L = 2.1 μm. Propagation of the laser pulse was simulated in all spatial dimensions, HHG was simulated on axis only. At small values of p the harmonic output grows quadratically with pressure. Due to SPM, the overall output becomes pressure-independent at large values of p in agreement with Eq. (26). The inset shows the dependence of the cut-off energy on the propagation distance.

Fig. 5.

Scaling law given by Eq. (32). The ionization rate of helium was calculated for a 2-cycle Gaussian laser pulse with a peak intensity adjusted to have a required value of the cut-off energy Ωcutoff. Only simulations with an ionization probability between 0.1% and 10% are shown in this plot.
