There are two types of the interferometer; Michelson type with delay lines and Fabry-Perot type with cavities for resonance. In either case very precise and elaborate control system of effective arm length is indispensable. Various noises on the laser interferometer are studied in detail. Theoretical limit to sensitivity for dimensionless amplitude h is determined by laser shot noise in photodetector. For 100km of beam path length and 1 Watt of laser power, this sensitivity limit is 10^<-21> Hz^<-1/2>. The results of the experiments so far in several laboratories are presented. The sensitivity of the order of h=10^<-18> Hz^<-1/2> has been obtained., 資料番号: SA0166065000}, pages = {1--36}, title = {レーザー干渉計による重力波検出}, volume = {25}, year = {1985} }
