Axion Search with Ring Cavity Experiment
Abstract
We suggest a novel experimental method to search for axion dark matter with an optical ring cavity. Our cavity measures the difference of the resonant frequencies between two circular-polarizations of the laser beam. Its technical design adopts double-pass configuration to realize a null experiment and reject environmental common-mode noises. We reveal that it can probe the axion-photon coupling constant with a broad range of axion mass $10^{-17} \text{eV} \lesssim m \lesssim 10^{-10} \text{eV}$, up to several orders of magnitude beyond the current limits. We expect that this cavity experiment establishes a new window to develop the axion research.
