Towards virtual-state superradiant lasing from cold ytterbium atoms — •Dmitriy Sholokhov, Hannes Gothe, Anna Breunig, and Jürgen Eschner — Universität des Saarlandes, Campus E2 6, 66123 Saarbrücken, Germany

We analyze atom-cavity interaction and lasing from cold Ytterbium-174 atoms that are magneto-optically trapped inside a high-finesse cavity. Lasing from a 399-nm (1S01P1) MOT was previously characterized for its power, frequency and polarization properties [1]. Here, we study a possibility of implementing a similar lasing process in a superradiant, or "bad-cavity", regime by employing narrower atomic transitions. We transport the atoms from blue (1S01P1) to green (1S03P1) MOT and characterize the associated dynamics of trapped atoms and spectral properties of the light emitted by the cavity under various conditions.
