We study the microlaser in an optical standing-wave cavity injected with two-level atoms. The results have shown the obvious influence of atomic centre-of-mass motion on the microlaser, such as the photon distribution, the linewidth and the frequency shift. It was found that when the momentum of atoms is comparable to that of photons, the influence of atomic motion is dominated and the number of photons in the microlaser can be greatly enhanced, owing to part of the atomic kinetic energy being transferred to the resonator. This work provides a comparison of the related studies on the atomic motion under special assumptions.
