Abstract We study the microlaser in an optical standing-wave cavity
injected with two-level atoms. The results showed the obvious influence of atomic center-of-mass motion on 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 microlaser can be greatly enhanced, owing to part of the atomic kinetic energy being transfered to the resonator. This work provides a comparison to the related studies on the atomic motion under special assumptions.
