Abstract

Helium atoms ionized by intense few-cycle light pulses in the barrier suppression regime emit spatially coherent extreme ultraviolet continuum extending to photon energies greater than Eph = 0.5 keV (λ <2.5 nm). The high-energy end of the continuum in the range of Eph ≥ 0.2 keV (λ ≤ 6 nm) was characterized spectrally over a considerable dynamic range using energy-dispersive detection. The sub-10-fs laser pulse duration was found to be crucial for generating radiation with the highest photon energies at the low (
