Abstract This paper describes trapping and laser cooling of a Ca+ ion in an rf quadrupole ion trap. A single Ca+ ion is laser cooled to below 130 mK and quantum jumps are observed by exciting the ion into the metastable D 5/2 state via the P 3/2 state. The lifetime of the metastable D 5/2 state is estimated from the distribution of the dark periods of the quantum-jump signal. Collision-induced jumps between the metastable D 3/2 state and the D 5/2 state in a background gas are also directly observed.
