Abstract:

Parametric instabilities have been predicted to occur in all advanced high optical power gravitational wave detectors. Here we analyze the parametric instability in power recycling and dual recycling interferometers with parameters close to advance LIGO configuration. We show that parametric instability occurs in all configurations with full power operation. We show that the level of parametric instability is critically determined by the resonant conditions of the recycling cavities of the interferometer.
