    Molecular beacons (MBs) of DCurrent treatments for human coronary artery disease necessitate the development of the next generations of vascular bioimplants. Recent reports provide evidence that controlling cell orientation ...
  • Dittmar, H.; Gäbler, F.; Stute, U. (Amsterdam : Elsevier B.V., 2013)
    Within this work the ablation behaviour of both carbon and glass fibre reinforced epoxy resin was assessed when ablated by a nanosecond-pulsed laser source emitting radiation in the ultra-violet spectrum. The investigation ...
  • Malobabic, Sina; Jupé, Marco; Ristau, Detlev (College Park, MD : American Institute of Physics, 2013)
    Nowadays, Ion Beam Sputter (IBS) processes are very well optimized on an empirical basis. To achieve further progresses, a modification of the IBS process by guiding the coating material using an axial magnetic field and ...
  • Lubatschowski, Holger (Amsterdam : Elsevier B.V., 2010)
    Ultrafast laser pulses have become a promising tool for microsurgery of the eye. Due to the low energy threshold, side effects are limited to the micrometer range This precision enables the use of ultrashort laser pulses ...
  • Hoff, Christian; Hermsdorf, Jörg; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2018)
    Hazardous substances such as unexploded ordnance represent a serious threat. It is necessary to develop new methods and equipment for their elimination. For this reason, a laser ablation process is developed where the shell ...
  • Cheng, Xinbin; Dong, Siyu; Zhi, Song; Paschel, Sebastian; Balasa, Istvan; Ristau, Detlev; Wang, Zhanshan (London : Nature Publishing Group, 2019)
    With the ever-increasing laser power and repetition rate, thermal control of laser media is becoming increasingly important. Except for widely used air cooling or a bonded heat sink, water cooling of a laser medium is more ...
  • Michael, Stefanie; Sorg, Heiko; Peck, Claas-Tido; Koch, Lothar; Deiwick, Andrea; Chichkov, Boris; Vogt, Peter M.; Reimers, Kerstin (San Francisco, California, US : PLOS, 2013)
    Tissue engineering plays an important role in the production of skin equivalents for the therapy of chronic and especially burn wounds. Actually, there exists no (cellularized) skin equivalent which might be able to ...
  • Kutrovskaya, S.; Arakelian, S.; Kucherik, A.; Osipov, A.; Evlyukhin, A.; Kavokin, A.V. (London : Nature Publishing Group, 2017)
    We show that the laser ablation method can be efficiently employed for the synthesis of silicon nanoparticles (NP), which are characterized by a strong resonant optical response in the visible spectral range. A single layer ...
  • Schütz, V.; Stute, U.; Horn, A. (Amsterdam : Elsevier B.V., 2013)
    Laser ablation of silicon is investigated with a large set of laser parameters to determine the ablation rate over five laser fluence decades. A thermodynamic model approach for the ablation of silicon has been derived. ...
  • Wippo, V.; Winter, Y.; Jaeschke, P.; Suttmann, O.; Overmeyer, L. (Amsterdam : Elsevier B.V., 2016)
    Presently, fiber reinforced materials are used for many industrial applications. Laser transmission welding (LTW) is a suitable method to join these materials. For multiple thermoplastics, the weld seam quality is affected ...
  • Sardana, Neha; Birr, Tobias; Schlenker, Sven; Reinhardt, Carsten; Schilling, Jörg (Bristol : IOP Publishing Ltd., 2014)
    The dispersion relation and propagation of surface plasmons polaritons (SPPs) on nanoporous gold films is experimentally investigated and an increasing red shift of the SPPs is observed with rising porosity. This is caused ...
  • Koch, Jürgen; Taschner, Sebastian; Suttmann, Oliver; Kaierle, Stefan (Amsterdam : Elsevier B.V., 2018)
    Functionalization by changing the topography of workpiece surfaces is interesting for many applications. Lasers - especially ultrashort pulse lasers - are flexible tools for this kind of tasks. Besides deterministic ...
  • Wippo, V.; Winter, Y.; Jaeschke, P.; Suttmann, O.; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2018)
    For the implementation of carbon fiber reinforced (CFRP) parts, these need to be assembled to more complex structures. Therefore, laser transmission welding was transferred to heat conduction welding for joining thermoplastic ...
  • Leschke, Jan; Barroi, Alexander; Kaierle, Stefan; Hermsdorf, Jörg; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2016)
    In this paper, an underwater laser cutting process for maintenance and replacement operations is presented and investigated regarding process robustness for the application in rough environments. A Yb:YAG laser is used ...
  • Emde, B.; Huse, M.; Hermsdorf, J.; Kaierle, Stefan; Wesling, V.; Overmeyer, Ludger; Kozakov, R.; Uhrlandt, D. (Amsterdam : Elsevier B.V., 2016)
    As an energy-preserving variant of laser hybrid welding, laser-assisted arc welding uses laser powers of less than 1 kW. Recent studies have shown that the electrical conductivity of a TIG welding arc changes within the ...
  • Walter, J.; Hustedt, M.; Wesling, V.; Barcikowski, S. (Amsterdam : Elsevier B.V., 2011)
    Laser welding and soldering are important industrial joining processes. As is known, LGACs (Laser Generated Air Contaminants) cause costs for environmental measures during production of complex metallic components (steel, ...
  • Yan, J.; Hao, H.; Li, J.Y.; Mikhailov, S.F.; Popov, V.G.; Vinokurov, N.A.; Huang, S.; Wu, J.; Günster, S.; Wu, Y.K. (College Park, MD : American Physical Society, 2016)
    We report a systematic experimental study of a storage ring two-color free-electron laser (FEL) operating simultaneously in the infrared (IR) and ultraviolet (UV) wavelength regions. The two-color FEL lasing has been ...
