Reducing the mirrors coating noise in laser gravitational-wave antennae by means of double mirrors
arXiv:gr-qc/0406071 · doi:10.1016/j.physleta.2004.10.078
Abstract
Recent researches show that the fluctuations of the dielectric mirrors coating thickness can introduce a substantial part of the future laser gravitational-wave antennae total noise budget. These fluctuations are especially large in the high-reflectivity end mirrors of the Fabry-Perot cavities which are being used in the laser gravitational-wave antennae. We show here that the influence of these fluctuations can be substantially decreased by using additional short Fabry-Perot cavities, tuned in anti-resonance instead of the end mirrors.
