Abstract:
In the framework of Dicke type models, a theory of laser radiation of two-level
systems is constructed. The theory uses the method of ordered operators, which
makes it possible to eliminate the atomic variables and obtain an asymptotically
exact (in the sense of the thermodynamic limit) hierarchy of equations for the
mean values, which depend only on the variables of the radiation. We also consider
the derivation of kinetic equations describing the radiation.
