Towards laser cooling and trapping of AlF molecules — •Simon Hofsäss1, Maximilian Doppelbauer1, Sebastian Kray1, Jesùs Pérez-Ríos1, Boris Sartakov2, Gerard Meijer1, and Stefan Truppe1 — 1Fritz-Haber-Institut der Max-Planck-Gesellschaft, Berlin, Germany — 2Faradayweg 4-6
We have recently identified the aluminium monofluoride (AlF) molecule as an excellent candidate for laser cooling and trapping at high densities and measured the detailed energy level structure of the electronic states relevant for these processes[1].
Here we report the characterization of a cryogenic buffer gas molecular beam of AlF that will be used to load a magneto optical trap (MOT). Spectroscopic techniques are applied to determine properties of the beam source such as molecular flux, velocity distribution and beam divergence. We investigate the optical cycling process on the rotationally closed Q lines of the main cooling transition and compare the measurements to a theoretical model.
