Magneto-optical traps (MOTs) are a workhorse for laser cooling of atoms and were recently extended to molecules. Yet, new mechanisms for molecular trapping and cooling are still an open area of exploration. Here, the authors show a blue-detuned MOT based on a conveyor-belt effect for CaF molecules, yielding higher number densities, comparable with some atomic MOTs.
