Transient analysis of continuous-wave lasing from cold Ytterbium atoms — •Anna Breunig, Dmitriy Sholokhov, Hannes Gothe, and Jürgen Eschner — Universität des Saarlandes, Experimentalphysik, 66123 Saarbrücken
We analyse lasing from cold Ytterbium-174 atoms that are magneto-optically trapped inside a 5 cm long high-finesse cavity. Trapping and cooling happens on the 1S0−1P1 transition. The atoms are laterally pumped on the 1S0−3P1 transition and emit frequency-shifted light into the cavity. This lasing relies on a two photon process including the trap light and was previously characterized for its power, frequency and polarization properties [1]. Here, we focus on the transient dynamics when the trap or pump light is switched on or off.
