Quadrature-witness readout for backscatter mitigation in gravitational-wave detectors limited by back-action
Niels Böttner, Roman Schnabel, Mikhail Korobko
Disturbances in gravitational wave (GW) observational data are often caused by non-stationary noise in the detector itself, such as back-scattering of laser stray light into the si…
Simultaneous Speedmeter and Position-Meter Response in a Single Tabletop Interferometer
Mikhail Korobko, Xiang Li, Torben Sobottke +3
Quantum radiation-pressure noise (QRPN) limits the low-frequency sensitivity of gravitational wave detectors. The established method for suppressing QRPN is the injection of freque…
Optical sensitivities of current gravitational wave observatories at higher kHz, MHz and GHz frequencies
Roman Schnabel, Mikhail Korobko
GEO 600, Kagra, LIGO, and Virgo were built to observe gravitational waves at frequencies in the audio band, where the highest event rates combined with the largest signal to noise…
Observation of Noise Suppression during High-Efficiency Wavelength Doubling of Intense Quasi-Monochromatic Laser Light
Julian Gurs, Mikhail Korobko, Christian Darsow-Fromm +2
Ultra-stable, quasi-monochromatic laser light forms the basis for high-precision interferometric measurements, e.g. for observing gravitational waves and for time keeping with opti…
Coherent feedback for quantum expander in gravitational wave observatories
Niels Böttner, Joe Bentley, Roman Schnabel +1
The observation of gravitational waves from binary neutron star mergers offers insights into properties of extreme nuclear matter. However, their high-frequency signals in the kHz…
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…
Squeezed-light interferometry on a cryogenically-cooled micro-mechanical membrane
Lisa Kleybolte, Pascal Gewecke, Andreas Sawadsky +2
Squeezed states of light reduce the signal-normalized photon counting noise of measurements without increasing the light power and enable fundamental research on quantum entangleme…
Observation of generalized optomechanical coupling and cooling on cavity resonance
Andreas Sawadsky, Henning Kaufer, Ramon Moghadas Nia +4
Optomechanical coupling between a light field and the motion of a cavity mirror via radiation pressure plays an important role for the exploration of macroscopic quantum physics an…
