G. Heinzel et al., Automatic beam alignment in the Garching 30-m prototype of a laser-interferometric gravitational wave detector, OPT COMMUN, 160(4-6), 1999, pp. 321-334
We describe a system for complete autoalignment of a suspended, power-recyc
led Michelson interferometer. All ten angular degrees of freedom are contro
lled by servo systems, thus ensuring optimal interference and fixing all be
ams in space. The methods and results are applicable to laser-interferometr
ic gravitational wave detectors, and possibly also to other types of sensit
ive interferometers. (C) 1999 Elsevier Science B.V. All rights reserved. PA
