One-dimensional model potentials optimized for the calculation of the HHG spectrum
Krisztina Sallai, Szabolcs Hack, Szilárd Majorosi +1
Based on the favourable properties of previously used one-dimensional (1D) atomic model potentials, we introduce a novel 1D atomic model potential for the 1D simulation of the quan…

Sándor Varró, Szabolcs Hack, Gábor Paragi +3
We present a general mathematical procedure to handle interactions described by a Morse potential in the presence of a strong harmonic excitation. We account for permanent and fiel…
Generation of micro-Joule level coherent quasi-continuum extreme ultraviolet radiation using multi-cycle intense laser-atom interactions

Attosecond multi-photon multi-electron dynamics
M. Kretschmar, A. Hadjipittas, B. Major +6
Multi-electron dynamics in atoms and molecules very often occur on sub- to few-femtosecond timescales. The available intensities of extreme-ultraviolet (XUV) attosecond pulses have…

We investigate the electron quantum path interference effects during high harmonic generation in atomic gas medium driven by ultrashort chirped laser pulses. To achieve that, we id…
High-order phase-dependent asymmetry in the above-threshold ionization plateau
M. Kübel, P. Wustelt, Y. Zhang +17
Above-threshold ionization spectra from cesium are measured as a function of the carrier-envelope phase (CEP) using laser pulses centered at 3.1 m wavelength. The directional as…
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…

Quantum mechanically, photoionization can be fully described by the complex photoionization amplitudes that describe the transition between the ground state and the continuum state…
Reconstruction of attosecond pulses in the presence of interfering dressing fields using the 100 kHz ELI-ALPS HR-1 laser system
