    Ultra-short laser applications require high quality dielectric optics. The natural dispersion of light needs to be matched by dielectric components. However such dispersive components are very challenging for the deposition ...
  • Schlichting, S.; Willemsen, Thomas; Ehlers, H.; Morgner, Uwe; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    In the presented work a fast frequency domain measurement system to determine group delay (GD) and group delay dispersion (GDD) of optical coatings is proposed. The measurements are performed in situ directly on moving ...

    Sheet-bulk metal forming is a new production process capable of performing deep-drawing and massive forming steps in a single operation. However, due to the high forming forces of the forming process, continuous process ...
  • Willemsen, Thomas; Jupé, Marco; Gyamfi, Mark; Schlichting, Sebastian; Ristau, Detlev (Washington, DC : Optical Society of America, 2017)
    Dielectric components are essential for laser applications. Chirped mirrors are applied to compress the temporal pulse broadening crucial in the femtosecond regime. However, the design sensitivity and the electric field ...
  • Willemsen, Thomas; Schlichting, S.; Gyamfi, M.; Jupé, Marco; Ehlers, H.; Morgner, Uwe; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The present contribution is addressed to an improved method to fabricate dielectric dispersive compensating mirrors (CMs) with an increased laser induced damage threshold (LIDT) by the use of ternary composite layers. ...
