  • High-order harmonic generation directly from a filament 
    Steingrube, D.S.; Schulz, E.; Binhammer, Thomas; Gaarde, M.B.; Couairon, A.; Morgner, Uwe; Kovacev, M. (Bristol : IOP Publishing Ltd., 2011)
    The synthesis of isolated attosecond pulses (IAPs) in the extreme ultraviolet (XUV) spectral region has opened up the shortest time scales for timeresolved studies. It relies on the generation of high-order harmonics (HHG) ...
  • Improving weld bead homogeneity in short arc GMAW processes applying low power diode lasers 
    Leschke, Jan; Zokoll, Erik; Hermsdorf, Jörg; Kaierle, Stefan (Amsterdam : Elsevier B.V., 2018)
    Using laser and arc power in equal parts, laser-arc hybrid welding processes are successfully adapted by the industry. This paper shows the stabilizing effects of diode lasers on short arc GMAW (gas metal arc welding) which ...
  • Nanofabrication of High-Resolution Periodic Structures with a Gap Size Below 100 nm by Two-Photon Polymerization 
    Zheng, Lei; Kurselis, Kestutis; El-Tamer, Ayman; Hinze, Ulf; Reinhardt, Carsten; Overmeyer, Ludger; Chichkov, Boris (New York : Springer New York LLC, 2019)
    In this paper, approaches for the realization of high-resolution periodic structures with gap sizes at sub-100 nm scale by two-photon polymerization (2PP) are presented. The impact of laser intensity on the feature sizes ...
