Cryogenic Mechanical Loss of GaAs/AlGaAs Crystalline Coatings
Nicholas A. Didio, Steven D. Penn, Satoshi Tanioka +3
Optical coatings with minimal thermal noise are essential for high-precision, laser-based metrology experiments. Substrate-transferred crystalline GaAs/AlGaAs coa…
Birefringence of AlGaAs/GaAs Coatings under Above-Band-Gap Illumination, GR Noise and Photo-Optic Transfer Function
Bin Wu, Shreyan Goswami, Satoshi Tanioka +1
AlGaAs/GaAs coatings are being considered as coating candidates for gravitational-wave detectors. In this paper we investigate the birefringence properties of this crystalline semi…
Criteria for identifying and evaluating locations that could potentially host the Cosmic Explorer observatories
Kathryne J. Daniel, Joshua R. Smith, Stefan Ballmer +19
Cosmic Explorer (CE) is a next-generation ground-based gravitational-wave observatory that is being designed in the 2020s and is envisioned to begin operations in the 2030s togethe…
Study on electro-optic noise in crystalline coatings toward future gravitational wave detectors
Satoshi Tanioka, Daniel Vander-Hyde, Garrett D. Cole +2
Thermal noise in high-reflectivity mirror coatings is a limiting factor in ground-based gravitational wave detectors. Reducing this coating thermal noise improves the sensitivity o…
Point Absorber Limits to Future Gravitational-Wave Detectors
W. Jia, H. Yamamoto, K. Kuns +198
High-quality optical resonant cavities require low optical loss, typically on the scale of parts per million. However, unintended micron-scale contaminants on the resonator mirrors…
LIGOs Quantum Response to Squeezed States
L. McCuller, S. E. Dwyer, A. C. Green +194
Gravitational Wave interferometers achieve their profound sensitivity by combining a Michelson interferometer with optical cavities, suspended masses, and now, squeezed quantum sta…
