Axion dark matter differentiates the phase velocities of the circular-polarized photons. In [Phys. Rev. Lett. 123, 111301 (2019)], we have proposed a scheme to measure the phase difference by using a linear optical cavity. If the scheme is applied to the Fabry-Perot arm of Advanced LIGO-like (Cosmic-Explorer-like) gravitational wave detector, the potential sensitivity to the axion-photon coupling constant, g aγ, reaches g aγ ≃ 8 10-13 GeV-1 (4 10-14 GeV-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 g aγ ≃ 10-14 GeV-1 (8 10-17 GeV-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.
