The embodiment of the invention provides a CPT atomic clock physical system and a method for realizing the same. The CPT atomic clock physical system comprises: a light source device configured to provide coherent two-color light; a beam splitting component which is configured to perform beam splitting on the coherent double colors so as to form a first beam of linearly polarized light and a second beam of linearly polarized light of which the polarization directions are perpendicular to each other; a quarter-wave plate which is configured to convert the first beam of linearly polarized light into circularly polarized light; an atomic gas chamber, wherein alkali metal atoms and inert gas are arranged in the atomic gas chamber, a magnetic field coil is arranged in the atomic gas chamber, and the atomic gas chamber is configured to receive the circularly polarized light and form emergent light; a first photoelectric detector which is configured to detect the second beam of linearly polarized light; and a second
