AB  - Extending the spectrum of attosecond pulses obtained via high-harmonic generation toward higher photon-energies is an important goal for attosecond spectroscopy.An extension of the cut-off photon energy of the high-harmonic spectrum is observed when the process is driven by non-sinusoidal waveforms with durations down to belowa single optical cycle. Specifically, while the phase-matched high-harmonic spectra generated in Neon by a ßinusoidal" pulse, with a wavelength of 1.6 μm and durationof 1.5 optical cycles, extends up to  350 eV, the spectra driven by a non-sinusoidal pulse, with a central wavelength of 1.4 μm and duration down to 0.5 optical cycles,extends up to  400 eV.This shows experimentally how non-sinusoidal sub-cycle waveforms violate the well known proportionality of the cut-off photon energy with the square of the central wavelength.
