Michelson interferometer with diffractively-coupled arm resonators in second-order Littrow configuration
Michael Britzger, Maximilian H. Wimmer, Alexander Khalaidovski +7
Michelson-type laser-interferometric gravitational-wave (GW) observatories employ very high light powers as well as transmissively- coupled Fabry-Perot arm resonators in order to r…
Diffractively coupled Fabry-Perot resonator with power-recycling
Michael Britzger, Daniel Friedrich, Stefanie Kroker +6
We demonstrate the optical coupling of two cavities without light transmission through a substrate. Compared to a conventional coupling component, that is a partially transmissive…
Waveguide grating mirror in a fully suspended 10 meter Fabry-Perot cavity
Daniel Friedrich, Bryan W. Barr, Frank Brückner +14
We report on the first demonstration of a fully suspended 10m Fabry-Perot cavity incorporating a waveguide grating as the coupling mirror. The cavity was kept on resonance by readi…
Realization of a monolithic high-reflectivity cavity mirror from a single silicon crystal
Frank Brückner, Daniel Friedrich, Tina Clausnitzer +6
We report on the first experimental realization of a high-reflectivity cavity mirror that solely consists of a single silicon crystal. Since no material was added to the crystal, t…
All-reflective coupling of two optical cavities with 3-port diffraction gratings
Oliver Burmeister, Michael Britzger, André Thüring +4
The shot-noise limited sensitivity of Michelson-type laser interferometers with Fabry-Perot arm cavities can be increased by the so-called power-recycling technique. In such a sche…
