Superradiant lasing in inhomogeneously broadened ensembles with spatially varying coupling
Anna Bychek, Christoph Hotter, David Plankensteiner +1
Theoretical studies of superradiant lasing on optical clock transitions predict a superb frequency accuracy and precision closely tied to the bare atomic linewidth. Such a superrad…

Continuous narrowband lasing with coherently driven V-level atoms
Christoph Hotter, David Plankensteiner, Helmut Ritsch
Simultaneous strong coherent pumping of the two transitions of a V-level atom with very differentdecay rates has been predicted to create almost perfect inversion on the narrower t…

Superradiant Cooling, Trapping, and Lasing of Dipole-Interacting Clock Atoms
Christoph Hotter, David Plankensteiner, Laurin Ostermann +1
A cold atomic gas with an inverted population on a transition coupled to a field mode of an optical resonator constitutes a generic model of a laser. For quasi-continuous operation…
