Abstract

Large ring lasers with a cavity Q well above 1012 are characterized by extremely narrow line-widths and high coherence. At this point, active Sagnac interferometers do not quite reach the quantum limit. In this paper, we will explore the current status of this technology and look at the various noise processes involved with large ring lasers rigidly mounted to the Earth crust.
