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 TiO 2 to Ta 2 O 5 in Ta 2 O 5 /SiO 2 coatings reduces the internal friction and in addition present data confirming it reduces thermal noise. We also show that TiO 2 -doped Ta 2 O 5 /SiO 2 coatings are close to satisfying the optical absorption requirements of second generation gravitational-wave detectors.
