Two-XUV-photon double ionization of Neon studied at the Extreme Light Infrastructure (ELI-ALPS)
I. Orfanos, E. Skantzakis, A. Nayak +12
Two XUV-photon double ionization of Ne, induced by an intense few-pulse attosecond train with a ~ 4 fs envelope duration is investigated experimentally and theoretically. The exper…
Temporal characterization of long quantum-path high harmonics
A. Carpeggiani, B. Bodi, E. S. Skantzakis +5
We measure for the first time the duration of long-quantum path EUV high harmonics produced in xenon gas. The long-quantum path contribution to the high-harmonic signal was careful…
Multiple ionization of argon via xuv-photon absorption induced by 20-gigawatt high-harmonic pulses
A. Nayak, I. Orfanos, I. Makos +10
We report the observation of multiple ionization of Argon through multi-XUV-photon absorption induced by an unprecedentedly powerful laser driven high-harmonic-generation source. C…
Extreme-ultraviolet pump-probe studies of one femtosecond scale electron dynamics
P. Tzallas, E. Skantzakis, L. A. A. Nikolopoulos +2
Studies of ultrafast dynamics along with femtosecond-pulse metrology rely on non-linear processes, induced solely by the exciting/probing pulses or the pulses to be characterized.…
