Thermal Noise in Optical Coatings: A Rigorous Opto-Mechanical Comparison of Nanolaminates and Isotropic Mixtures
Vincenzo Pierro, Vincenzo Fiumara, Veronica Granata +1
We investigate whether a perfectly ordered periodic nanolaminate is intrinsically less mechanically dissipative than an isotropic co-sputtered mixture designed to provide the exact…
Thermal Noise Reduction in Ternary Optical Coatings: From Ti::GeO-Based Ternary Systems to High Index Materials
Vincenzo Pierro, Guerino Avallone, Jessica Steinlechner +11
Minimizing coating thermal noise is crucial for enhancing gravitational wave detector sensitivity, with a target Amplitude Spectral Density Reduction Factor (ASD RF) of relat…
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…
