  • Willemsen, T.; Brinkmann, M.; Jupé, M.; Gyamfi, M.; Schlichting, S.; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    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 ...
  • 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 ...
  • Kanyou Nana, R.; Korte, S.; Dickmann, S.; Garbe, Heyno; Sabath, F. (Göttingen : Copernicus GmbH, 2009)
    The threat of ultra wideband (UWB) sources is interesting for military issues. This paper summarizes information concerning the voltages generated from some commercially available UWB generator systems and their produced ...
  • 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. ...
  • Höfer, B.; Zhang, J.; Wildmann, J.; Zallo, E.; Trotta, R.; Ding, Fei; Rastelli, A.; Schmidt, O.G. (College Park, ML : American Institute of Physics Inc., 2017)
    Independent tuning of emission energy and decay time of neutral excitons confined in single self-assembled In(Ga)As/GaAs quantum dots is achieved by simultaneously employing vertical electric fields and lateral biaxial ...
  • Shi, Liping; Andrade, Jose R.C.; Kim, Hyunwoong; Han, Seunghwoi; Nicolas, Rana; Franz, Dominik; Boutu, Willem; Heidenblut, Torsten; Segerink, Frans B.; Bastiaens, Bert; Merdji, Hamed; Kim, Seung-Woo; Morgner, Uwe; Kovačev, Milutin (American Institute of Physics Inc., 2017)
    We propose to use diabolo nanoantennas for experimentally investigating the origin of the enhanced third harmonic generation by localized surface plasmon polaritons. In such a geometry, the opposing apexes of bowties are ...
  • Paoletti, U.; Garbe, Heyno; John, W. (Göttingen : Copernicus GmbH, 2005)
    Two simple techniques for the measurement of the shielding efficiency for the electric field of a symmetric enclosure are presented.y They allow measurements in the symmetry plane of the enclosure without disturbances b ...
  • Borchert, M.J.; Blessing, P.E.; Devlin, J.A.; Harrington, J.A.; Higuchi, T.; Morgner, J.; Smorra, C.; Wursten, E.; Bohman, M.; Wiesinger, M.; Mooser, A.; Blaum, K.; Matsuda, Y.; Ospelkaus, C.; Quint, W.; Walz, J.; Yamazaki, Y.; Ulmer, S. (College Park, MD : American Physical Society, 2019)
    We report on the first detailed study of motional heating in a cryogenic Penning trap using a single antiproton. Employing the continuous Stern-Gerlach effect we observe cyclotron quantum transition rates of 6(1) quanta/h ...
  • Mente, D.; Greiff, M.; Mathis, Wolfgang (Göttingen : Copernicus GmbH, 2007)
    Modern numerical methods for field calculations are having problems dealing with singularities correctly. This paper provides two alternative methods that are able to handle electric fields including singularities in ...
