Substrate-transferred GaAs/AlGaAs crystalline coatings for gravitational-wave detectors: A review of the state of the art
G. D. Cole, S. Ballmer, G. Billingsley +16
In this Perspective we summarize the status of technological development for large-area and low-noise substrate-transferred GaAs/AlGaAs (AlGaAs) crystalline coatings for interferom…
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…
Exploration of co-sputtered TaO-ZrO thin films for gravitational-wave detectors
M. Abernathy, A. Amato, A. Ananyeva +45
We report on the development and extensive characterization of co-sputtered tantala-zirconia thin films, with the goal to decrease coating Brownian noise in present and future grav…
Apparatus to Measure Optical Scatter of Coatings Versus Annealing Temperature
Joshua R. Smith, Rana X Adhikari, Katerin M. Aleman +9
Light scattered by amorphous thin-film optical coatings limits the sensitivity of interferometric gravitational-wave detectors. We describe an imaging scatterometer to assess the r…
Mechanical Ringdown Studies of Large-Area Substrate-Transferred GaAs/AlGaAs Crystalline Coatings
Steven D. Penn, Maya M. Kinley-Hanlon, Ian A. O. MacMillan +5
We investigated elastic loss in GaAs/AlGaAs multilayers to help determine the suitability of these coatings for future gravitational wave detectors. We measured large (…
Mapping the Optical Absorption of a Substrate-Transferred Crystalline AlGaAs Coating at 1.5um
Jessica Steinlechner, Iain W Martin, Angus Bell +5
The sensitivity of 2nd and 3rd generations of interferometric gravitational wave detectors will be limited by thermal noise of the test-mass mirrors and highly reflective coatings.…
