Abstract

Mirror thermal noise in Ta2O5/SiO2 coatings is predicted to be the limiting noise in the 50-300 Hz frequency range in the interferometric gravitational wave detectors. Ta2O5 losses were dominating compared to the SiO2 losses. We developed a model to calculate multilayer mechanical losses and we are working for low mechanical losses Ta2O5/SiO2 coatings
