The big BaF chill

Heavy barium monofluoride molecules are getting cold! See our latest preprint for a new approach to implement laser cooling for this and other complex molecular species that are in high demand for precision measurements of fundamental physics.

Less is more

To realize the cooling, we have designed and implemented custom optical spectra that optimize laser cooling forces. Our work shows that it is particularly important to optimize the laser light for the laser cooling of complex molecules.

Bring on the rare molecular isotopologues! 

For atoms, laser cooling is frequently used to cool different isotopes, or even collect rare isotopes. In our latest paper, we demonstrate such selective cooling for molecules for the first time, cooling both 138BaF and 136BaF molecules!
