Towards a MOT of AlF molecules — •Sid Wright — Fritz-Haber-Institut der Max Planck Gesellschaft, Berlin

Aluminium monofluoride (AlF) is a promising candidate for laser cooling and trapping. The primary laser cooling transition at 227.5 nm is extremely strong and highly vibrationally diagonal, making it feasible to slow a molecular beam from 200 m/s to rest in around 1 cm. This offers the potential to greatly increase the number and density of molecules available for ultracold experiments.

In this talk, I will present the latest progress towards a magneto-optical trap (MOT) of AlF molecules, focusing on the first laser slowing results, and our development of a slow, continuous molecular beam source.
