摘要：

Thermodynamical fluctuations of the temperature in mirrors of gravitational wave antennae are transformed through the thermal expansion coefficient into additional noise. This source of noise, which may also be interpreted as fluctuations due to thermoelastic damping, may not be neglected and leads to the necessity to reexamine the choice of materials for the mirrors. An additional source of noise are fluctuations of the mirrors' surfaces caused by optical power absorbed in dielectrical reflective layers. (C) 1999 Elsevier Science B.V. All rights reserved.
