  • Abstract
    We measured high-resolution spectra of high-order harmonics generated in the interaction of relativistic-irradiance (>1018 W/cm2) multi-terawatt femtosecond lasers with gas jets. The spectra exhibit very fine structures on the sub-eV scale, indicating temporal coherence of a few tens of femtoseconds.
