LIGO Detector Characterization in the Second and Third Parts of the Fourth Observing Run
J. Glanzer, A. F. Helmling-Cornell, A. Calafat +244
LIGO detector characterization efforts enabled the confident detection of gravitational waves from hundreds of compact binary coalescences during the fourth observing run. Reliable…
Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run
E. Goetz, A. Neunzert, A. M. Knee +258
We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…
Hyperloss from coherent spatial-mode mixing in quantum-correlated networks
Stephan Grebien, Julian Gurs, Roman Schnabel +1
Quantum-correlated networks distribute quantum resources such as squeezed and entangled states. These states are central to modern quantum technology, including photonic quantum co…
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…
Improving cosmological reach of a gravitational wave observatory using Deep Loop Shaping
Jonas Buchli, Brendan Tracey, Tomislav Andric +28
Improved low-frequency sensitivity of gravitational wave observatories would unlock study of intermediate-mass black hole mergers, binary black hole eccentricity, and provide early…
Advanced LIGO detector performance in the fourth observing run
E. Capote, W. Jia, N. Aritomi +193
On May 24th, 2023, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), joined by the Advanced Virgo and KAGRA detectors, began the fourth observing run for a t…
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…
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…
