Influence of Young’s modulus temperature dependence on parametric instability in Advanced LIGO interferometer

We discuss the influence of Young’s modulus temperature dependence on the number of parametrically unstable modes in a Fabry-Perot cavity of Advanced LIGO interferometer. Some unstable modes may be suppressed by changing the mirror’s temperature due to temperature dependence of Young’s modulus. Vary...
