  • Biomechanical Effects of a Cross Connector in Sacral Fractures – A Finite Element Analysis 
    Gierig, Meike; Liu, Fangrui; Weiser, Lukas; Lehmann, Wolfgang; Wriggers, Peter; Marino, Michele; Saul, Dominik (Lausanne : Frontiers Media, 2021)
    Background: Spinopelvic fractures and approaches of operative stabilization have been a source of controversial discussion. Biomechanical data support the benefit of a spinopelvic stabilization and minimally invasive ...
  • Carrier-envelope offset frequency stabilization of a thin-disk laser oscillator via depletion modulation 
    Andrade, José R.C.; Modsching, Norbert; Tajalli, Ayhan; Dietrich, Christian M.; Kleinert, Sven; Placzek, Fabian; Kreipe, Bernhard; Schilt, Stephane; Wittwer, Valentin J.; Südmeyer, Thomas; Morgner, Uwe (Piscataway : Institute of Electrical and Electronics Engineers, 2020)
    We present a novel concept for the stabilization of the carrier-envelope offset (CEO) frequency of femtosecond pulse trains from thin-disk laser oscillators by exploiting gain depletion modulation in the active gain region. ...
  • 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 Power Femtosecond Doubly Resonant Optical Parametric Oscillator 
    Dietrich, Christian Markus (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    Optical parametric oscillators (OPOs), which rely on an optical parametric amplification in a cavity, can extend the available optical frequency range of common laser sources. In a doubly resonant OPO (DROPO) two optical ...
  • Laser Frequency Noise Stabilisation and Interferometer Path Length Differences on LISA Pathfinder 
    Paczkowski, S.; et al.; LPF Collaboration (Bristol : Institute of Physics Publishing, 2017)
    The LISA Pathfinder mission is a technology demonstrator for a LISA-like gravitational wave observatory in space. Its first results already exceed the expectations. This is also true for the optical metrology system which ...
  • Microbial community composition shapes enzyme patterns in topsoil and subsoil horizons along a latitudinal transect in Western Siberia 
    Schnecker, Jörg; Wild, Birgit; Takriti, Mounir; Eloy Alves, Ricardo J.; Gentsch, Norman; Gittel, Antje; Hofer, Angelika; Klaus, Karoline; Knoltsch, Anna; Lashchinskiy, Nikolay; Mikutta, Robert; Richter, Andreas (Amsterdam : Elsevier, 2015)
    Soil horizons below 30cm depth contain about 60% of the organic carbon stored in soils. Although insight into the physical and chemical stabilization of soil organic matter (SOM) and into microbial community composition ...
  • Multi-anionic and -cationic compounds: New high entropy materials for advanced Li-ion batteries 
    Wang, Qingsong; Sarkar, Abishek; Wang, Di; Velasco, Leonardo; Azmi, Raheleh; Bhattacharya, Subramshu S.; Bergfeldt, Thomas; Düvel, Andre; Heitjans, Paul; Brezesinski, Torsten; Hahn, Horst; Breitung, Ben (Cambridge : Royal Society of Chemistry, 2019)
    In the present work, a new class of high entropy materials for energy storage applications is introduced. Multi-anionic and -cationic compounds are prepared by facile mechanochemistry using a recently designed multi-cationic ...
  • Quantum limit of different laser power stabilization schemes involving optical resonators 
    Kwee, P.; Willke, Benno; Danzmann, Karsten (Bristol : IOP Publishing Ltd., 2010)
    Three different laser power stabilization schemes are compared: a traditional power stabilization, a traditional one with subsequent optical resonator, and a power stabilization with the novel optical ac coupling technique. ...
