Relativistic high-order harmonic spectrum. The sub-5-fs pulse is tightly focused [see Fig. 2 (e)] onto a glass target and the reflected beam is directed into an XUV spectrometer. (a) Single-shot angularly-resolved high-harmonic spectral intensity of the generated XUV radiation in a logarithmic colour scale. (b) Corresponding angular integration between 0–20 mrad of the spectral intensity showing photon energy cutoff up to 100 eV. Inset: high-order harmonics at the highest photon energies in a linear scale.
