Test of local Lorenz invariance using a double-cavity laser system

Abstract

We report the results of testing the local Lorentz invariance during five-month operation of a double-cavity laser system, where one cavity operates in a free generation mode while the frequency of the second cavity is stabilized with a nonlinear ultra-narrow absorption resonance of the methane molecule. An interpretation of the experimental results is given on the basis of the Robertson-Mansouri-Sexl formalism. © 2012 Pleiades Publishing, Ltd
