Paper Abstract

The problem of the coherent states generation with definite parameters for multilevel quantum systems is investigated. The interaction with external environment and stochastic fields can destroy of the coherence. The competition of these processes is considered on a base of Fokker - Planck Equations approach, deriving from master equation for the density matrix of the system. Examples of the coherent states dynamics for two-level atoms in an external stochastic field in the nonideal resonator are considered. Average over the realizations of stochastic fields is performed for the case of white gaussian noise and Kubo - Anderson process. Explicit formulas for transition probabilities, longitudinal and transversal relaxation times and shape of radiation line are obtained.
