  • Opto-Thermal simulation model for optimizing laser-excited remote phosphor systems 
    Chatzizyrli, Elisavet; Tinne, Nadine; Lachmayer, Roland; Neumann, Jörg; Kracht, Dietmar (Bellingham, Wash. : SPIE, 2018)
    A new family of lighting products is developed as laser diodes replace LEDs in the remote phosphor configuration. The resulting lighting systems, also known as laser-excited remote phosphor systems, exhibit advanced ...
  • Optoacoustic effect is responsible for laser-induced cochlear responses 
    Kallweit, N.; Baumhoff, P.; Krueger, A.; Tinne, N.; Kral, A.; Ripken, Tammo; Maier, H. (London : Nature Publishing Group, 2016)
    Optical stimulation of the cochlea with laser light has been suggested as an alternative to conventional treatment of sensorineural hearing loss with cochlear implants. The underlying mechanisms are controversially discussed: ...
  • Reduced wear and adhesion forces by laser dispersing of ceramics 
    Nölke, C.; Claußen, S.; Dudziak, S.; Haferkamp, H.; Barcikowski, S. (Amsterdam : Elsevier B.V., 2010)
    Laser dispersing offers a great potential to fabricate layers or tracks with tailored properties threat duce abrasive or adhesive wear at the surface of highly stressed components. Different ceramic powder materials like ...
  • Reliable copper spot welding with ir laser radiation through short prepulsing 
    Moalem, A.; Von Witzendorff, Philipp; Stute, U.; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2012)
    We demonstrate a technique, which significantly enhances the stability of copper welding with laser radiation. After modelling spot welding stability we conclude that oxide layer morphology typical for native oxide layers ...
  • SLM produced porous titanium implant improvements for enhanced vascularization and osteoblast seeding 
    Matena, Julia; Petersen, Svea; Gieseke, Matthias; Kampmann, Andreas; Teske, Michael; Beyerbach, Martin; Murua Escobar, Hugo; Haferkamp, Heinz; Gellrich, Nils-Claudius; Nolte, Ingo (Basel : MDPI AG, 2015)
    To improve well-known titanium implants, pores can be used for increasing bone formation and close bone-implant interface. Selective Laser Melting (SLM) enables the production of any geometry and was used for implant ...
  • Temperature issues with white laser diodes, calculation and approach for new packages 
    Lachmayer, Roland; Kloppenburg, Gerolf; Stephan, Serge (Bellingham, Wash. : SPIE, 2015)
    Bright white light sources are of significant importance for automotive front lighting systems. Today's upper class systems mainly use HID or LED light sources. As a further step laser diode based systems offer a high ...
  • Three-dimensional cell growth on structures fabricated from ORMOCER® by two-photon polymerization technique 
    Schlie, Sabrina; Ngezahayo, Anaclet; Ovsianikov, Aleksandr; Fabian, Tilman; Kolb, Hans-Albert; Haferkamp, Heinz; Chichkov, Boris (London : SAGE Publications Ltd., 2007)
    Two-photon polymerization technique was applied to generate three-dimensional (3D) scaffold-like structures using the photosensitive organic-inorganic hybrid polymer ORMOCER®. The structures were studied with respect to ...
  • Tissue Engineered Skin Substitutes Created by Laser-Assisted Bioprinting Form Skin-Like Structures in the Dorsal Skin Fold Chamber in Mice 
    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 ...
