  • FPGA based laser frequency stabilization using FM spectroscopy 
    Spindeldreier, Christian; Bartosch, Wolfgang; Wendrich, Thijs; Rasel, Ernst Maria; Ertmer, Wolfgang; Blume, Holger (Bellingham, Wash. : SPIE, 2018)
    Frequency stabilized light sources with narrow linewidth are mandatory for atom interferometry based experiments. For compact experiment designs used on space platforms, tunable DFB diode lasers are often used. These lasers ...
  • High-precision cavity spectroscopy using high-frequency squeezed light 
    Junker, J.; Wilken, D.; Huntington, E.; Heurs, Michèle (Washington, DC : The Optical Society, 2021)
    In this article, we present a novel spectroscopy technique that improves the signal-to-shot-noise ratio without the need to increase the laser power. Detrimental effects by technical noise sources are avoided by ...
  • High-resolution signal-in-space measurements of VHF omnidirectional ranges using UAS 
    Schrader, Thorsten; Bredemeyer, Jochen; Mihalachi, Marius; Ulm, David; Kleine-Ostmann, Thomas; Stupperich, Christoph; Sandmann, Sergei; Garbe, Heyno (Göttingen : Copernicus GmbH, 2019)
    In this paper, we describe measurement results of the signal-in-space of very high frequency (VHF) omnidirectional range (VOR) facilities. In aviation VOR are used to display the current course of the aircraft in the ...
