Magneto-optical trapping of Zinc

We report on laser cooling and magneto-optical trapping of atomic zinc. The atoms are cooled using the 213.9,nm ${}^1$S${}_0$ $\to$ ${}^1$P${}_1$ transition, making this the shortest wavelength employed for magneto-optical trapping thus far. We demonstrate trapping of all stable isotopes of zinc, including the fermionic isotope ${}^{67}$Zn, which features a very narrow ${}^1$S${}_0$ $\to$ ${}^3$P${}_0$ transition that could form the basis of an optical atomic clock. We characterize the influence of various parameters on the MOT population and loading rate. The results presented here constitute the first step towards the application of zinc for high-precision optical spectroscopy and quantum information processing.
