Atomic Coherence in the Micromaser Injected withSlow V-type Three-State Atoms: Emission Probability

The effects of atomic coherence on the single-mode two-photon micromaser injected with slow V-type three-state atoms are studied for the first time. It is shown that the atomic coherence can modify the atomic emission probability. The effects of the atomic centre-of-mass momentum, the cavity length and other parameters are also studied.
