Title: Laser instrumentation for multi-mode gravitational radiation detectors

Abstract

In multi-mode detectors, the antenna displacements can be amplified 400 times at the last resonator. Sensing these displacements with laser illuminated Fabry-Perot interferometers is discussed here. Laser shot noise and back action on the detector would be at the level of one phonon with cavity power of 10 watts and cavity finesse of {similar to}30000. This would correspond to {delta}h values of the order of 3.5 10{sup {minus}22}/{radical}Hz over a bandwidth of 700 Hz for a 1200 kg five-mode detector operating at 1600 Hz.
