Low-temperature, high-density magneto-optical trapping of potassium using the open 4S-5P transition at 405 nm

D. C. McKay, D. Jervis, D. J. Fine +3

We report the laser cooling and trapping of neutral potassium on an open transition. Fermionic 40K is captured using a magneto-optical trap (MOT) on the closed 4S-4P transition at…
