Axion dark matter differentiates the phase velocities of the circular-polarized photons. In Phys.Rev.Lett. 123 (2019) no.11, 111301, we have proposed a scheme to measure the phase difference by using a linear optical cavity. If the scheme is applied to the Fabry-P\'erot arm of Advanced LIGO-like (Cosmic-Explorer-like) gravitational wave detector, the potential sensitivity to the axion-photon coupling constant, gaγ, reaches gaγ≃8×10−13GeV−1(4×10−14GeV−1) at the axion mass m≃3×10−13 eV (2×10−15 eV) and remains at around this sensitivity for 3 orders of magnitude in mass. Furthermore, its sensitivity has a sharp peak reaching gaγ≃10−14GeV−1(8×10−17GeV−1) at m=1.563×10−10 eV (1.563×10−11 eV). This sensitivity can be achieved without loosing any sensitivity to gravitational waves.
