  • 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 ...
  • Robot based remote laser cutting of three-dimensional automotive composite parts with thicknesses up to 5mm 
    Bluemel, S.; Bastick, S.; Staehr, R.; Jaeschke, P.; Suttmann, O.; Kaierle, Stefan; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2018)
    With the intention to develop a robot based laser cutting process for automotive 3D parts with varying thickness consisting of carbon fibre reinforced plastics (CFRP), strategies of 2D investigations were adapted. The used ...
  • Simulation of straight and bent self-written waveguides in photopolymer mixture using phenomenological and diffusion models 
    Suar, Monali; Rahlves, Maik; Reithmeier, Eduard; Roth, Bernhard (Bellingham, Wash. : SPIE, 2018)
    Straight and bent self-written waveguides (SWWs) are formed within a photomonomer mixture by means of a self-trapping effect when a single laser beam or two laser beams with tilt are propagated inside. These SWWs can be ...
  • Studies on the robustness of underwater laser cutting of S355J2+N using a Yb:YAG disk laser source 
    Leschke, Jan; Barroi, Alexander; Kaierle, Stefan; Hermsdorf, Jörg; Overmeyer, Ludger (Amsterdam : Elsevier B.V., 2016)
    In this paper, an underwater laser cutting process for maintenance and replacement operations is presented and investigated regarding process robustness for the application in rough environments. A Yb:YAG laser is used ...
  • 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 influence of laser welding processes on the weld seam quality of thermoplastic composites with high moisture content 
    Wippo, V.; Winter, Y.; Jaeschke, P.; Suttmann, O.; Overmeyer, L. (Amsterdam : Elsevier B.V., 2016)
    Presently, fiber reinforced materials are used for many industrial applications. Laser transmission welding (LTW) is a suitable method to join these materials. For multiple thermoplastics, the weld seam quality is affected ...
  • 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 ...
  • Wave packet echoes in the motion of trapped atoms 
    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 ...
