Trapping of cold Cs2 triplet ground state molecules in an optical dipole trap — •Peter Staanum1,2, Stephan Kraft1, Jörg Lange1, Roland Wester1, and Matthias Weidemüller1 — 1Physikalisches Institut, Universität Freiburg, Hermann-Herder Strasse 3, 79104 Freiburg — 2Institut für Quantenoptik, Universität Hannover, Welfengarten 1, 30167 Hannover
We present the status of an experiment which aims at studying Cs2 molecules in the a 3Σu+ triplet ground state. The molecules are formed from a sample of laser cooled Cs atoms by photoassociation and state-sensitively detected using two-photon ionization and time-of-flight mass spectrometry. The optical dipole trap formed by the focus of a CO2 laser represents a quasi-electrostatic trap which enables simultaneous trapping of molecules and atoms (Li and Cs in our case) and hence facilitates studies of atom-molecule collisions, molecule-molecule collisions and chemical reactions involving cold Cs2 molecules.
