    "abstract": "We demonstrate broadband laser cooling of atomic ions in an rf trap using\nultrafast pulses from a modelocked laser. The temperature of a single ion is\nmeasured by observing the size of a time-averaged image of the ion in the known\nharmonic trap potential. While the lowest observed temperature was only about 1\nK, this method efficiently cools very hot atoms and can sufficiently localize\ntrapped atoms to produce near diffraction-limited atomic images.",
