J. Mizuno et al., RESONANT SIDE-BAND EXTRACTION - A NEW CONFIGURATION FOR INTERFEROMETRIC GRAVITATIONAL-WAVE DETECTORS, Physics letters. A, 175(5), 1993, pp. 273-276
We introduce a new Fabry-Perot based interferometric gravitational wav
e detector that, compared with previous designs, greatly decreases the
amount of power that must be transmitted through optical substrates t
o obtain a given light power in its arms. This significantly reduces t
he effects of wavefront distortions caused by heating due to absorptio
n in the optics, and allows an improved broadband sensitivity to be ac
hieved.
