  • Henkel, Jost; Lein, Manfred; Engel, Volker; Dreissigacker, Ingo (College Park, MD : American Physical Society, 2012)
    By solving the time-dependent Schrödinger equation for atoms in short laser pulses of different polarizations, it is shown that in strong-field ionization without rescattering, the lateral width of the electron-momentum ...
  • Henkel, Jost; Lein, Manfred (College Park, MD : American Physical Society, 2015)
    Two-color ionization of atoms with a strong 800-nm fundamental component and a weak 400-nm component with perpendicular polarization gives detailed insight into the ionization dynamics. When the delay between the two colors ...
  • Chacon, Alexis; Lein, Manfred; Ruiz, Camilo (College Park, MD : American Physical Society, 2014)
    Ionization by an attosecond pulse launches an electron wave packet in the continuum which contains rich information about the pulse, the parent system, and the ionization dynamics. This emission process is not instantaneous ...
  • Zhao, Jing; Lein, Manfred (College Park, MD : American Physical Society, 2013)
    From the numerical solution of the time-dependent Schrödinger equation, we obtain the times of ionization and return of the laser-driven electron in high-order harmonic generation by probing the dynamics with a second ...
  • Henkel, Jost; Lein, Manfred; Engel, Volker (College Park, MD : American Physical Society, 2011)
    We present quantum-mechanical studies on above-threshold ionization of molecular ions in two and three dimensions. The momentum distributions show signatures of interfering emissions from the molecular centers. These ...
  • van der Zwan, Elmar V.; Lein, Manfred (College Park, MD : American Physical Society, 2012)
    Accurate molecular imaging via high-order harmonic generation relies on comparing harmonic emission from a laser-irradiated molecule and an adequate reference system. However, an ideal reference atom with the same ionization ...
  • Schmitt-Sody, Andreas; Kurz, Heiko G.; Bergé, Luc; Skupin, Stefan; Polynkin, Pavel (Bristol : Institute of Physics Publishing, 2016)
    The propagation of intense picosecond laser pulses in air in the presence of strong nonlinear self-action effects and air ionization is investigated experimentally and numerically. The model used for numerical analysis is ...
  • Pabst, Stefan; Lein, Manfred; Wörner, Hans Jakob (College Park, MD : American Physical Society, 2016)
    Strong-field ionization (SFI) has been shown to prepare wave packets with few-femtosecond periods. Here, we explore whether this technique can be extended to the attosecond time scale. We introduce an intuitive model, which ...
  • Shvetsov-Shilovski, N.I.; Lein, Manfred; Madsen, L.B.; Räsänen, E.; Lemell, C.; Burgdörfer, J.; Arbó, D.G.; Tokési, K. (College Park, MD : American Physical Society, 2016)
    We present a semiclassical two-step model for strong-field ionization that accounts for path interferences of tunnel-ionized electrons in the ionic potential beyond perturbation theory. Within the framework of a classical ...
  • Petersen, Ingo; Henkel, Jost; Lein, Manfred (College Park, MD : American Physical Society, 2015)
    Strong-field ionization of aligned diatomic and polyatomic molecules such as O2, N2, C2H4, and others in circularly polarized laser fields is investigated theoretically. By calculating the emission-angle-resolved lateral ...
  • Jürgens, P.; Jupé, M.; Gyamfi, M.; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The modeling of the laser-induced damage processes can be divided into thermal and electronic processes. Especially, electronic damage seems to be well understood. In corresponding models, the damage threshold is linked ...
