  We study a single-level quantum dot strongly coupled to a superconducting
lead and tunnel-coupled to a normal electrode which can exchange energy with a
single-mode resonator. We show that a such system can sustain lasing
characterized by a sub-Poissonian Fock-state distribution of the resonator. The
lasing regime is clearly identifiable in the subgap transport regime: in the
resonant case, the current is pinned to the maximum value achievable in this
hybrid nanostructure.
