Zeeman slowing of CaF — •Mariia Stepanova, Timo Poll, Paul Kaebert, Supeng Xu, Mirco Siercke, and Silke Ospelkaus — Institut für Quantenoptik, Leibniz Universität Hannover

Our Zeeman slowing scheme for laser-cooling of molecules with favorable Franck-Condon factors promises a substantial increase in molecular number in the velocity range of under 20 m/s, which is required for loading a Magneto-Optical Trap (MOT). The scheme stands out in its ability to not only lower the initial mean velocity of the molecular beam, but also to compress the velocity distribution in a continuous fashion. In this talk, we will present our most recent status on the experiment to achieve the goal of slowing and cooling CaF molecules generated from a buffer gas cell source, followed by our efforts to implement a dual-frequency MOT without sub-Doppler heating, discussed in [1].
