We connect three phenomena in which a coherent electromagnetic field could be generated: polariton
condensation, phase-locking in arrays of underdamped Josephson junctions, and lasing. All
these phenomena have been described using Dicke-type models of spins coupled to a single photon
mode. These descriptions may be distinguished by whether the spins are quantum or classical, and
whether they are strongly or weakly damped.
