Abstract

Reducing thermal noise from optical coatings is crucial to reaching the required sensitivity in next generation interferometric gravitational-wave detectors. Here we show that adding TiO2 to Ta2O 5 in Ta2O5/SiO2 coatings reduces the internal friction and in addition present data confirming it reduces thermal noise. We also show that TiO2-doped Ta2O 5/SiO2 coatings are close to satisfying the optical absorption requirements of second generation gravitational-wave detectors. © 2007 IOP Publishing Ltd.
