  • Carrier-Wave Rabi-Flopping Signatures in High-Order Harmonic Generation for Alkali Atoms 

    Ciappina, M. F; Pérez-Hernández, J. A.; Landsman, A. S.; Zimmermann, T.; Lewenstein, Maciej; Roso, L.; Krausz, F. (APS Physics, 2015-04-08)
    Article
    Open Access
    We present a theoretical investigation of carrier-wave Rabi flopping in real atoms by employing numerical simulations of high-order harmonic generation (HHG) in alkali species. Given the short HHG cutoff, related to the ...
  • High-order harmonic generation driven by plasmonic fields: a new route towards the generation of UV and XUV photons? 

    Ciappina, M. F.; Pérez-Hernández, J. A.; Roso, L.; Zaïr, A.; Lewenstein, Maciej (IOP, 2015-04-16)
    Article
    Open Access
    We present theoretical investigations of high-order harmonic generation (HHG) resulting from the interaction of noble gases with different kind of temporally and spatially synthesized laser fields. These fields, based on ...
  • Strong-field plasmonic photoemission in the mid-IR at <1 GW/cm2 intensity 

    Teichmann, S. M.; Rácz, P.; Ciappina, M. F.; Pérez-Hernández, J. A.; Thai, A.; Fekete, J.; Elezzabi, A. Y.; Veisz, L.; Biegert, J.; Dombi, P. (Nature Publishing group, 2015-01-12)
    Article
    Open Access
    We investigated nonlinear photoemission from plasmonic films with femtosecond, mid-infrared pulses at 3.1 mm wavelength. Transition between regimes of multi-photon-induced and tunneling emission is demonstrated at an ...
