摘要：

172Yb+ ions in an rf trap have been laser cooled for the first time by driving the 2S1/2-2P1/2 transition at 369.5 nm. It was necessary to irradiate the ions with 2.438 μm infra-red radiation to depopulate the metastable 2D3/2 state. An upper limit on ion energies was determined by observing the size of the trapped cloud and corresponds to a temperature below 2 K. Cooled ion lineshapes were compared with simulations and coherence nulls were observed in the infra-red frequency scans. © 1990 Springer-Verlag.
