  In a recent article, Alli and Sewell formulated a new version of the
Dicke-Hepp-Lieb laser model in terms of quantum dynamical semigroups, and
thereby extended the macroscopic picture of the model. In the present article,
we complement that picture with a corresponding microscopic one, which carries
the following new results. (a) The local microscopic dynamics of the model is
piloted by the classical, macroscopic field, generated by the collective action
of its components; (b) the global state of the system carries no correlations
between its constituent atoms after transient effects have died out; and (c) in
the latter situation, the state of the system at any time $t$ maximises its
entropy density, subject to the constraints imposed by the instantaneous values
of its macroscopic variables.
