Designing a low-loss high reflectivity mirror for gravitational waves detectors by combining a dielectric metasurface and a multilayer stack
Edith Hartmann, Michel Lequime, Jerome Degallaix +4
The design of low-mechanical-loss, high reflectivity mirrors is crucial in the development of the next generation of gravitational-wave observatories. Currently, the amorphous mult…

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…
