Positional control of mirrors in a laser gravitational-wave interferometer with radiation recycling

摘要

The problem of separation of the alignment-error signals, resulting from perturbations of separate mirrors, is considered for a laser gravitational-wave interferometer representing a full combined Fabry—Perot—Michelson scheme with radiation recycling. The Anderson method framework is used to show that such separation can easily be attained subject to some restrictions imposed on the recycling-cavity finesse.
