Polarization analysis of lasing from cold Ytterbium atoms — •Dmitriy Sholokhov, Hannes Gothe, Anna Breunig, and Jürgen Eschner — Universität des Saarlandes, Saarbrücken
We analyse the laser process from cold Ytterbium atoms that are magneto-optically trapped inside a 5 cm long high-finesse cavity. The atoms are laterally pumped to one of the three 3P1 Zeeman sub levels and emit frequency-shifted light into the cavity. This lasing relies on a two photon process including trap light and was previously characterized for its power and frequency properties [1]. Here, we focus on the polarization dependence between pump and cavity output and infer information about the spatial position of the lasing atoms.
