Towards an ultracold gas of polar molecules — •Karin Mörtlbauer, Christian Glück, Jörg Lange, Johannes Deiglmayr, Anna Grochola, Roland Wester, and Matthias Weidemüller — Albert-Ludwigs Universität, Physikalisches Institut, Hermann-Herder-Str. 3, 79104 Freiburg i.Brsg., Germany

We recently demonstrated the formation of ultracold LiCs molecules by the trapping light of a double species magneto optical trap [1] and also achieved the active photoassociation of dipolar LiCs molecules in the same setup. In order to create a stable and large ensemble of ultracold LiCs molecules, we will form the molecules in an optical dipole trap [2] and transfer them into the absolute ro-vibrational ground state relying on a Raman-type relaxation scheme and radiative decay. Estimates for the transfer efficiency are derived and the current status of the experimental setup is described.
