A two-level atomic-state micro-laser model was established under non-rotational approximation. The evolution of the operator of the cavity density in the micro-labyrinthine system with the injected atoms is investigated considering the virtual light field effect. It is shown that the virtual photon introduces the virtual light field quantum noise to the open system in the form of two-photon oscillations.
