Abstract: | We perform a calculation of the linewidth of a micromaser, using
the master equation
and the quantum regression approach. A `dephasing' contribution is
identified from pumping processes that conserve the photon number
and do not appear in the photon statistics. We work out examples for
a single-atom maser with a precisely controlled coupling and for a
laser where the interaction time is broadly distributed.
In the latter case, we also assess the convergence of a
recently developed uniform Lindblad approximation to the master
equation; it is relatively slow. |
