Demonstration of length control for a filter cavity with coherent control sidebands
Naoki Aritomi, Yuhang Zhao, Eleonora Capocasa +22
For broadband quantum noise reduction of gravitational-wave detectors, a frequency-dependent squeezed vacuum field realized using a filter cavity is the most promising technique an…
GEO600 beam splitter thermal compensation system: new design and commissioning
Séverin Nadji, Holger Wittel, Nikhil Mukund +8
Gravitational waves have revolutionised the field of astronomy by providing scientists with a new way to observe the universe and gain a better understanding of exotic objects like…
Characterization and evasion of backscattered light in the squeezed-light enhanced gravitational wave interferometer GEO 600
Fabio Bergamin, James Lough, Emil Schreiber +15
Squeezed light is injected into the dark port of gravitational wave interferometers, in order to reduce the quantum noise. A fraction of the interferometer output light can reach t…
A vertical inertial sensor with interferometric readout
S. L. Kranzhoff, J. Lehmann, R. Kirchhoff +9
High precision interferometers such as gravitational-wave detectors require complex seismic isolation systems in order to decouple the experiment from unwanted ground motion. Impro…
Improving the stability of frequency dependent squeezing with bichromatic control of filter cavity length, alignment and incident beam pointing
Yuhang Zhao, Eleonora Capocasa, Marc Eisenmann +21
Frequency dependent squeezing is the main upgrade for achieving broadband quantum noise reduction in upcoming observation runs of gravitational wave detectors. The proper frequency…
First demonstration of 6 dB quantum noise reduction in a kilometer scale gravitational wave observatory
James Lough, Emil Schreiber, Fabio Bergamin +14
Photon shot noise, arising from the quantum-mechanical nature of the light, currently limits the sensitivity of all the gravitational wave observatories at frequencies above one ki…
