LIGO A: Detector Design and Science Prospects Beyond A+
L. Sun, K. Kuns, B. J. J. Slagmolen +1153
We present the LIGO A detector concept, an upgrade for the LIGO observatories based on room-temperature interferometers beyond the fifth observing run (O5). Building on th…
Photodiode quantum efficiency for 2-μm light in the signal band of gravitational wave detectors
Julian Gurs, Nils Sueltmann, Christian Darsow-Fromm +2
Quantum technologies with quantum correlated light require photodiodes with near-perfect `true' quantum efficiency, the definition of which adequately accounts for the photodiode d…
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…
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 at 2128 nm for future gravitational-wave observatories
Christian Darsow-Fromm, Julian Gurs, Roman Schnabel +1
All gravitational-wave observatories (GWOs) have been using the laser wavelength of 1064 nm. Ultra-stable laser devices are at the sites of GEO 600, Kagra, LIGO and Virgo. Since 20…
Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO and Advanced Virgo's first three observing runs
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1589
We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo det…
Constraints on cosmic strings using data from the third Advanced LIGO-Virgo observing run
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1586
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 data set. Search results are presented for gravitational waves produced b…
Population Properties of Compact Objects from the Second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1338
We report on the population of the 47 compact binary mergers detected with a false-alarm rate 1/yr in the second LIGO--Virgo Gravitational-Wave Transient Catalog, GWTC-2. We observ…
Tests of General Relativity with Binary Black Holes from the second LIGO-Virgo Gravitational-Wave Transient Catalog
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1344
Gravitational waves enable tests of general relativity in the highly dynamical and strong-field regime. Using events detected by LIGO-Virgo up to 1 October 2019, we evaluate the co…
Highly-efficient generation of coherent light at 2128 nm via degenerate optical-parametric oscillation
Christian Darsow-Fromm, Maik Schröder, Julian Gurs +2
Cryogenic operation in conjunction with new test-mass materials promises to reduce the sensitivity limitations from thermal noise in gravitational-wave detectors. The currently mos…
Open data from the first and second observing runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1245
Advanced LIGO and Advanced Virgo are actively monitoring the sky and collecting gravitational-wave strain data with sufficient sensitivity to detect signals routinely. In this pape…
NQontrol: An open-source platform for digital control-loops in quantum-optical experiments
Christian Darsow-Fromm, Luis Dekant, Stephan Grebien +3
Experiments in quantum optics often require a large number of control loops, e.g. for length-stabilization of optical cavities and control of phase gates. These control loops are g…
