Journal ArticleDOI
Diffractive Optics for Gravitational Wave Detectors
A. Bunkowski,Oliver Burmeister,Tina Clausnitzer,Ernst-Bernhard Kley,Andreas Tünnermann,Karsten Danzmann,Roman Schnabel +6 more
TL;DR: In this article, an all-reflective Fabry-Perot interferometer concept in 2nd order Littrow mount is investigated and the input-output relations for such a resonator are derived treating the grating coupler by means of a scattering matrix formalism.
Journal ArticleDOI
Optical testbed for the LISA phasemeter
Thomas S. Schwarze,G. Fernández Barranco,Daniel Penkert,Oliver Gerberding,Gerhard Heinzel,Karsten Danzmann +5 more
TL;DR: In this paper, the authors show the planning and advances in the implementation of an optical testbed for the full metrology chain based on an ultra-stable hexagonal optical bench, which allows the generation of three unequal heterodyne beatnotes with a zero phase combination.
Proceedings ArticleDOI
Low-loss gratings for next-generation gravitational wave detectors
Tina Clausnitzer,Ernst-Bernhard Kley,Andreas Tünnermann,A. Bunkowski,Oliver Burmeister,Karsten Danzmann,Roman Schnabel,Angela Duparré,Stefan Gliech +8 more
TL;DR: By combining electron beam lithography with coating processes, very shallow gratings with diffraction efficiencies between 0.02% and 7% have been realized as discussed by the authors, and the application of such gratings as coupling components to a reflective Fabry-Perot cavity resulted in a finesse of more than 400.

TL;DR: For almost 20 years, advanced techniques have been developed and tested at the GEO 600 laser-interferometric gravitational wave detector as mentioned in this paper, and these techniques have influenced the upgrades of other detectors worldwide.
LISA-like Laser Ranging for GRACE Follow-on
Daniel Schütze,G. Stede,Vitali Müller,Oliver Gerberding,Christoph Mahrdt,Benjamin Sheard,Gerhard Heinzel,Karsten Danzmann +7 more
TL;DR: In this article, the basic concept of the Laser Ranging Interferometer for GRACE follow-on is described and a testbed is presented to investigate its functionality and key components, which can potentially improve the inter-satellite range measurements.
