Thermoelastic-damping noise from sapphire mirrors in a fundamental-noise-limited interferometer
arXiv:gr-qc/0410028 · doi:10.1103/PhysRevLett.93.241101
Abstract
We report the first high-precision interferometer using large sapphire mirrors, and we present the first direct, broadband measurements of the fundamental thermal noise in these mirrors. Our results agree well with the thermoelastic-damping noise predictions of Braginsky, et al. [Phys. Lett. A 264, 1(1999)] and Cerdonio, et al.[Phys. Rev. D 63, 082003 (2001)], which have been used to predict the astrophysical reach of advanced interferometric gravitational wave detectors.
