Squeezing the quantum noise of a gravitational-wave detector below the standard quantum limit
Wenxuan Jia, Victoria Xu, Kevin Kuns +168
Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental…
30 W ultra-stable laser light at 2128 nm for future gravitational-wave observatories
Julian Gurs, Nina Bode, Christian Darsow-Fromm +5
Thermal noise of the dielectric mirror coatings can limit laser-optical high-precision measurements. Coatings made of amorphous silicon and silicon nitride could provide a remedy f…
Point absorbers in Advanced LIGO
Aidan F. Brooks, Gabriele Vajente, Hiro Yamamoto +198
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations a…
Quasi Monolithic Fiber Collimators
Jonathan Joseph Carter, Steffen Böhme, Kevin Weber +6
Interferometric displacement measurements, especially in space interferometry applications, face challenges from thermal expansion. Bonded assemblies of ultra-low thermal expansion…
