One of the fundamental results used in observational cosmology is the distance duality relation (DDR), which relates the luminosity distance, DL, with angular diameter distance, DA, at a given redshift z. We employ the observed limits of this relation to constrain the coupling of axionlike particles (ALPs) with photons. With our detailed 3D ALP-photon mixing simulation in standard ΛCDM universe and latest DDR limits observed in Holanda and Barros [Phys. Rev. D 94, 023524 (2016)].PRVDAQ2470-001010.1103/PhysRevD.94.023524 we limit the coupling constant gφ≤6×10-13 GeV-1(nGBMpc) for ALPs of mass ≤10-15 eV. The DDR observations can provide very stringent constraint on ALPs mixing in the future. Also any deviation in DDR can be conventionally explained as photons decaying to axions or vice-versa.
