Mw. Regehr et al., DEMONSTRATION OF A POWER-RECYCLED MICHELSON INTERFEROMETER WITH FABRY-PEROT ARMS BY FRONTAL MODULATION, Optics letters, 20(13), 1995, pp. 1507-1509
Large-scale gravitational-wave detectors currently under construction
such as the LIGO detectors use multiple-mirror resonant optical system
s containing several surfaces at which the relative phase of interferi
ng light beams must be controlled. We describe a tabletop experiment t
hat demonstrates a scheme for extracting signals in such an interferom
eter corresponding to deviations from perfect interference.
