  • 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 ...
  • Identification of the predicted 5s-4f level crossing optical lines with applications to metrology and searches for the variation of fundamental constants 
    Windberger, A.; Crespo López-Urrutia, J.R.; Bekker, H.; Oreshkina, N.S.; Berengut, J.C.; Bock, V.; Borschevsky, A.; Dzuba, V.A.; Eliav, E.; Harman, Z.; Kaldor, U.; Kaul, S.; Safronova, U.I.; Flambaum, V.V.; Keitel, C.H.; Schmidt, Piet O.; Ullrich, J.; Versolato, O.O. (College Park, MD : American Physical Society, 2015)
    We measure optical spectra of Nd-like W, Re, Os, Ir, and Pt ions of particular interest for studies of a possibly varying fine-structure constant. Exploiting characteristic energy scalings we identify the strongest lines, ...
