Laser interferometry experiments on light-speed anisotropy

Abstract

Although gas lasers provide highly coherent light sources useful in interferometer experiments, their application to the measurement of light-speed anisotropy can produce inconclusive results unless reflection effects at mirror surfaces are taken fully into account. A recent experiment by Brillet and Hall is discussed and shown to indicate a local anisotropy due solely to earth rotation. © 1981.
