Experimental Realization of Optimized Ternary Mirror Coatings
V. Pierro, M. Granata, C. Michel +9
We report on the first experimental realization of multi-material dielectric mirror coatings designed through a multi-objective optimization algorithm to simultaneously minimize th…

Development of ion-beam sputtered silicon nitride thin films for low-noise mirror coatings of gravitational-wave detectors
A. Amato, M. Bazzan, G. Cagnoli +32
Brownian thermal noise of thin-film coatings is a fundamental limit for high-precision experiments based on optical resonators such as gravitational-wave interferometers. Here we p…

Comparison of arm cavity optical losses for the two wavelengths of the Einstein Telescope gravitational wave detector
Maxime Le Jean, Jerome Degallaix, David Hofman +8
A new generation of gravitational wave detectors is currently being designed with the likely use of a different laser wavelength compared to current instruments. The estimation of…
