Search for Cosmic Axions using an Optical Interferometer
Abstract
A high finesse optical cavity can be used to search for cosmic axions in the mass range 10-6< ma <10-4 eV. Either a two-arm or a single-arm cavity is suitable and in either case the signal as resonant sidebands imposed on the carrier. Assuming for the local axion density the usual figure of 500 MeV/cm3 [8], the KSVZ axion line [4] g/ma = 0.4 Gev-2, can be reached over the full mass range in a one year search.
