Abstract
The large scale interferometric gravitational wave detectors consist of Fabry-Perot cavities operating at very high powers ranging from tens of kW to MW. The high powers may result in several nonlinear effects which would affect the performance of the detector. In this article I will consider two such major effects which could result in degrading the performance of the detector. The first is the thermal distortion of the mirrors due to temperature gradients and the second is effect of radiation pressure which can displace the freely hanging mirrors. Both these effects tend to drive the cavity out of resonance degrading the optimal performance of the detector. These effects are likely to be important in the optimal functioning of the full-scale interferometers such as the VIRGO and LIGO.
