Title: Laser instrumentation for one-phonon sensitivity and wide bandwidth with multimode gravitational radiation detectors

Abstract

In a multimode detector of gravitational radiation, the displacements induced in the antenna by the gravitational field can be amplified by many orders at the last resonator. Detection of the displacements of that resonator with a Fabry--Perot interferometer is considered. Quantum and classical sources of noise are analyzed and specifications for laser instrumented massive wideband systems operating at the level of deltah = 2.6 x 10/sup -20/ and 3 x 10/sup -22//(Hz)/sup 1/2/ are given. Three detectors could be used to cover the frequency range approx. =400--approx. =1200 Hz with approximately uniform sensitivity.
