A Novel Scheme for Slowing Molecules — •Maurice Petzold, Mirco Siercke, Paul Kaebert, Philipp Gersema, and Silke Ospelkaus — Institut für Quantenoptik, Leibniz Universität Hannover

Current efforts to directly cool molecules to degeneracy are largely limited by the flux of slow molecules available in experiments. While slowing methods for molecules have been available for a long time, they have not been able to achieve efficiencies comparable to methods used for atoms. In this poster, we present our ideas for novel slowing methods of molecules. We propose a novel scheme based on radiative forces to slow down molecules to trappable velocities. The magneto-optical scheme is continuous and provides compression of the 1D-velocity distribution. We give detailed calculations of the forces obtained for the case of SrF and give estimates for the expected flux of cold molecules. To demonstrate the feasibility of our approach, we report on progress on applying our method to a thermal beam of Potassium atoms.
