We modeled an atomic beam micromaser experiment [G. Rempe et al. : Phys. Rev. Lett. 58 (1987) 353] as well as a more recently reported cavity-QED experiment of a similar type [M. Brune et al. : Phys. Rev. Lett. 76 (1996) 1800] using the theory of quantum trajectories in order to see to what degree agreement between theory and experiment can be achieved. We compared our computations with the analysis based upon a “quantum theory of micromaser” [P. Filipowicz et al. : Phys. Rev. A 34 (1986) 3077] for the purpose of reliability check. We found rather nonnegligible differences between the results of theories and of experiments.

In recent experiments it was demonstrated that number or Fock states of the one-atom maser can be generated. Two types of experiments have been performed. In the first one the Fock states are achieved in steady state via the so-called trapping states of the micromaser field. In the second experiment the number states were generated in a dynamical experiment by state reduction. In the latter case the generated field was afterwards probed by observing the dynamics of a probe atom in the field. The fact that Fock states of the micromaser field can be realised leads to new applications of the micromaser one of them is the generation of a many particle entanglement of the GHZ type.
