  • Diffractive optics for gravitational wave detectors 
    Bunkowski, A.; Burmeister, O.; Clausnitzer, T.; Kley, E.-B.; Tünnermann, A.; Danzmann, Karsten; Schnabel, R. (Bristol : Institute of Physics Publishing, 2006)
    All-reflective interferometry based on nano-structured diffraction gratings offers new possibilities for gravitational wave detection. We investigate an all-reflective Fabry-Perot interferometer concept in 2nd order Littrow ...
  • Mechanical Q-factor measurements on a test mass with a structured surface 
    Nawrodt, Ronny; Zimmer, A.; Koettig, T.; Clausnitzer, T.; Bunkowski, A.; Kley, E.B.; Schnabel, Roman; Danzmann, Karsten; Nietzsche, S.; Vodel, W.; Tuennermann, A.; Seidel, P. (Bristol : IOP Publishing Ltd., 2007)
    We present mechanical Q-factors (quality factors) of a crystalline quartz test mass with a nano-structured surface, measured in the temperature regime from 5 to 300 K. The nano-structure was a grating with a period of 2 ...
  • Phase and alignment noise in grating interferometers 
    Freise, A.; Bunkowski, A.; Schnabel, R. (Bristol : IOP Publishing Ltd., 2007)
    Diffraction gratings have been proposed as core optical elements in future laser interferometric gravitational-wave detectors. In this paper, we derive equations for the coupling between alignment noise and phase noise at ...
  • Power-recycled michelson interferometer with a 50/50 grating beam splitter 
    Friedrich, Daniel; Burmeister, O.; Britzger, M.; Bunkowski, A.; Clausnitzer, T.; Fahr, S.; Kley, E.B.; Tünnermann, A.; Danzmann, Karsten; Schnabel, Roman (Bristol : IOP Publishing Ltd., 2008)
    We designed and fabricated an all-reflective 50/50 beam splitter based on a dielectric grating. This beam splitter was used to set up a power-recycled Michelson interferometer with a finesse of about FPR ≈ 880. Aspects of ...
