  • Construction of an optical test-bed for eLISA 
    Lieser, Maike; Fitzsimons, E.; Isleif, Katharina-Sophie; Killow, C.; Perreur-Lloyd, M.; Robertson, D.; Schuster, S.; Tröbs, Michael; Veith, S.; Ward, H.; Heinzel, Gerhard; Danzmann, Karsten (Bristol : Institute of Physics Publishing, 2016)
    In the planned eLISA mission a key part of the system is the optical bench that holds the interferometers for reading out the inter-spacecraft distance and the test mass position. We report on ongoing technology development ...
  • Doppler Cooling and Trapping on Forbidden Transitions 
    Binnewies, T.; Wilpers, G.; Sterr, U.; Riehle, F.; Helmcke, J.; Mehlstäubler, T.E.; Rasel, Ernst Maria; Ertmer, Wolfgang (American Physical Society, 2001)
    Ultracold atoms at temperatures close to the recoil limit have been achieved by extending Doppler cooling to forbidden transitions. A cloud of 40Ca atoms has been cooled and trapped to a temperature as low as 6μK by operating ...
  • Gravitational wave detectors 
    Aufmuth, Peter; Danzmann, Karsten (Bristol : Institute of Physics Publishing, 2005)
    The existence of gravitational radiation is a prediction of Einstein's general theory of relativity. Gravitational waves are perturbations in the curvature of spacetime caused by accelerated masses. Since the 1960s ...
  • Interferometer-Type Structures for Guided Atoms 
    Dumke, R.; Müther, T.; Volk, M.; Ertmer, Wolfgang; Birkl, G. (American Physical Society, 2002)
    We experimentally demonstrate interferometer-type guiding structures for neutral atoms based on dipole potentials created by microfabricated optical systems. As a central element we use an array of atom waveguides being ...
  • Line of sight calibration for the laser ranging interferometer on-board the GRACE follow-On mission: On-ground experimental validation 
    Koch, Alexander; Sanjuan, Josep; Gohlke, Martin; Mahrdt, Christoph; Brause, Nils Christopher; Braxmaier, Claus; Heinzel, Gerhard (Washington, DC : Optical Society of America, 2018)
    The laser ranging interferometer (LRI) on board of the GRACE follow-on spacecraft, launched in May 2018, is the first laser interferometer to perform an inter-satellite range measurement. It is designed for ranging noise ...
  • Low noise 400 W coherently combined single frequency laser beam for next generation gravitational wave detectors 
    Wellmann, Felix; Bode, Nina; Wessels, Peter; Overmeyer, Ludger; Neumann, Jörg; Willke, Benno; Kracht, Dietmar (Washington, DC : Optica, 2021)
    Design studies for the next generation of interferometric gravitational wave detectors propose the use of low-noise single-frequency high power laser sources at 1064 nm. Fiber amplifiers are a promising design option because ...
  • A low-power, low-noise 37-MHz photoreceiver for intersatellite laser interferometers using discrete heterojunction bipolar transistors 
    Barranco, German Fernandez; Sheard, Benjamin S.; Dahl, Christian; Mathis, Wolfgang; Heinzel, Gerhard (Piscataway, NJ : Institute of Electrical and Electronics Engineers Inc., 2018)
    Intersatellite laser interferometers feature quadrant photoreceivers to produce electrical signals from the interfered optical beams. In the particular case of LISA, the expected optical AC beat note has an amplitude of ...
  • Observation of phase fluctuations in elongated bose-einstein condensates 
    Dettmer, S.; Hellweg, D.; Ryytty, P.; Arlt, Jan J.; Ertmer, Wolfgang; Sengstock, K.; Petrov, D.S.; Shlyapnikov, G.V.; Kreutzmann, H.; Santos, Luis; Lewenstein, M. (American Physical Society, 2001)
    The occurrence of phase fluctuations due to thermal excitations in Bose-Einstein condensates (BECs) is studied for a variety of temperatures and trap geometries. We observe the statistical nature of the appearance of phase ...
  • Picosecond laser filamentation in air 
    Schmitt-Sody, Andreas; Kurz, Heiko G.; Bergé, Luc; Skupin, Stefan; Polynkin, Pavel (Bristol : Institute of Physics Publishing, 2016)
    The propagation of intense picosecond laser pulses in air in the presence of strong nonlinear self-action effects and air ionization is investigated experimentally and numerically. The model used for numerical analysis is ...
  • Quantum noise limits to simultaneous quadrature amplitude and phase stabilization of solid-state lasers 
    Huntington, E.H.; Harb, C.C.; Heurs, Michèle; Ralph, T.C. (College Park, MD : American Physical Society, 2007)
    A quantum mechanical model is formulated to describe the coupling between pump intensity noise and laser frequency noise in a solid-state laser. The model allows us to investigate the limiting effects of closed-loop ...
  • Subwavelength population density gratings in resonant medium created by few-cycle pulses 
    Arkhipov, R.M.; Arkhipov, M.V.; Pakhomov, A.V.; Babushkin, I.; Demircan, A.; Morgner, Uwe; Rosanov, N.N. (Bristol : Institute of Physics Publishing, 2017)
    We consider theoretically recently proposed a new possibility of creation, erasing and ultrafast control of population density grating. Such grating can be created in resonant medium when ultrashort pulses with duration ...
  • The TRAPSENSOR facility: An open-ring 7 tesla Penning trap for laser-based precision experiments 
    Gutiérrez, Manuel J.; Berrocal, Joaquín; Cornejo, Juan M.; Domínguez, Francisco; Del Pozo, Jesús J.; Arrazola, Iñigo; Bañuelos, Javier; Escobedo, Pablo; Kaleja, Oliver; Lamata, Lucas; Rica, Raúl A.; Schmidt, Stefan; Block, Michael; Solano, Enrique; Rodríguez, Daniel (Bristol : Institute of Physics Publishing, 2019)
    A Penning-trap facility for high-precision mass spectrometry based on a novel detection method has been built. This method consists in measuring motional frequencies of singly-charged ions trapped in strong magnetic fields ...
  • Three-beam atom interferometer 
    Hinderthür, H.; Pautz, A.; Rieger, V.; Ruschewitz, F.; Peng, J.L.; Sengstock, K.; Ertmer, Wolfgang (American Physical Society, 1997)
    We present an atom interferometer based on the interference of three partial matter waves in three different internal and external states. Coherent laser excitation acts as a beamsplitter to create a superposition state ...

    Buchkremer, F.B.J.; Dumke, R.; Levsen, H.; Birkl, G.; Ertmer, Wolfgang (American Physical Society, 2000)
    A new echo technique to access the coherent and dissipative dynamics of atomic wave packet oscillations in trapping potentials was experimentally and systematically validated. By using this technique, the coherence time ...
