  • Boosting terahertz generation in laser-field ionized gases using a sawtooth wave shape 
    Martínez, P.G.D.A.; Babushkin, I.; Bergé, L.; Skupin, S.; Cabrera-Granado, E.; Köhler, C.; Morgner, Uwe; Husakou, A.; Herrmann, J. (American Physical Society, 2015)
    Broadband ultrashort terahertz (THz) pulses can be produced using plasma generation in a noble gas ionized by femtosecond two-color pulses. Here we demonstrate that, by using multiple-frequency laser pulses, one can obtain ...
  • Brazing in SiH4-Doped Inert Gases: A New Approach to an Environment Friendly Production Process 
    Holländer, U.; Wulff, D.; Langohr, A.; Möhwald, K.; Maier, H.J. (Seoul : Korean Society for Precision Engineering, 2020)
    Engineering under protective atmospheres or in vacuum allows the production of materials and components, where the absence of oxygen is an essential requirement for a successful processing. Ideally, joining or coating of ...
  • Laser powder bed fusion of WE43 in hydrogen-argon-gas atmosphere 
    Abel, Arvid; Wessarges, Yvonne; Julmi, Stefan; Hoff, Christian; Hermsdorf, Jörg; Klose, Christian; Maier, Hans Jürgen; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2020)
    Growing demand for individual and especially complex parts with emphasis on biomedical or lightweight applications enhances the importance of laser powder bed fusion. Magnesium alloys offer both biocompatibility and low ...
  • Phase matching of high-order harmonics in a semi-infinite gas cell 
    Steingrube, Daniel S.; Vockerodt, Tobias; Schulz, Emilia; Morgner, Uwe; Kovačev, Milutin (American Physical Society, 2009)
    Phase matching of high-order harmonic generation is investigated experimentally for various parameters in a semi-infinite gas-cell (SIGC) geometry. The optimized harmonic yield is identified using two different noble gases ...
