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…

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…

Interferometer Techniques for Gravitational-Wave Detection
Charlotte Bond, Daniel Brown, Andreas Freise +1
Several km-scale gravitational-wave detectors have been constructed world wide. These instruments combine a number of advanced technologies to push the limits of precision length m…
