Paper Abstract
This paper reports on trapping and laser-cooling of singly-ionized strontium ions in a linear Paul trap. We
demonstrate loading of large ion clouds containing as much as 106 ions and laser cooling down to the Coulomb
crystal transition. We observe the spatial segregation of the different Sr+ isotopes due to the mass-dependent
Paul trap stiffness. Sympathetic cooling of the different isotopes is demonstrated, either by laser-cooling of 88Sr+
(83% abundance) or of 86Sr+ (10% abundance). These demonstrations open the way to the use of a large ion
Coulomb crystal for quantum optics and quantum information experiments, where the strong confinement, the
long lifetime, and the absence of perturbation by cooling lasers are crucial.
