Abstract

At the present date there are exist two models of the micromaser dynamics — with measurement of atomic state on output from resonator and without. In the literature [1] one has studied a form and different features of the quasistationary state of the field for the system without atomic state control. There is discussed a photon statistics that could be described by a central diagonal of the reduced density matrix (RDM) of the field in the basis of eigenvectors of the photon number operator. The form of a quasistationary state is determined by location of the so-called quasitrapping regions in the space of Fock’s number. The whole initial distribution is localized inside these regions forming states that we called quasitrapped (QTS), respectively. The quasistationary phase of the dynamics looks like a slow flux of the population of different photon numbers between closest QTS. Under some parameters of the model one can even observe a macroscopic superposition of several QTS. This model is based on deterministic recurrence relation that connecting RDM of the field before and after interaction with an atom. It is allowed in the theory to calculate a unique solution being given definite initial conditions for the micromaser.
