Generation of micro-Joule level coherent quasi-continuum extreme ultraviolet radiation using multi-cycle intense laser-atom interactions
Vassilis Tsafas, Theocharis Lamprou, Emmanouil Skantzakis +4
In the present work we report on the current progress of the recently constructed GW attosecond extreme ultraviolet (XUV) source developed at the Institute of Electronic Structure…
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…
Quantum path interferences in high-order harmonic generation from aligned diatomic molecules
S. Chatziathanasiou, I. Liontos, E. Skantzakis +8
Electron quantum path interferences in strongly laser-driven aligned molecules and their dependence on the molecular alignment is an essential open problem in strong-field molecula…
Reconstruction of attosecond pulses in the presence of interfering dressing fields using the 100 kHz ELI-ALPS HR-1 laser system
D. Hammerland, P. Zhang, S. Kuehn +7
Attosecond Pulse Trains (APT) generated by high-harmonic generation (HHG) of high-intensity near-infrared (IR) laser pulses have proven valuable for studying the electronic dynamic…

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…
Towards Quantum Information Processing at the Attosecond Timescale
I. K. Kominis, G. Kolliopoulos, D. Charalambidis +1
Coherent processing of quantum information and attosecond science had so far little in common. We here show that recent data in high harmonic emission reveal quantum information pr…
Revealing quantum path details in high-field physics
G. Kolliopoulos, B. Bergues, H. Schröder +5
The tunnelling of an electron through a suppressed atomic potential followed by its motion in the continuum, is the fundamental mechanism underlying strong-field laser-atom/molecul…
Tracing molecular dynamics at the femto-/atto-second boundary through extreme-ultraviolet pump-probe spectroscopy
P. A. Carpeggiani, P. Tzallas, A. Palacios +3
Coherent light pulses of few to hundreds of femtoseconds (fs) duration have prolifically served the field of ultrafast phenomena. While fs pulses address mainly dynamics of nuclear…
Extreme-ultraviolet pump-probe studies of one femtosecond scale electron dynamics
P. Tzallas, E. Skantzakis, L. A. A. Nikolopoulos +2
