    "abstract": "We demonstrate an ultraviolet diode laser system for cooling of trapped\nytterbium ions. The laser power and linewidth are comparable to previous\nsystems based on resonant frequency doubling, but the system is simpler, more\nrobust, and less expensive. We use the laser system to cool small numbers of\nytterbium ions confined in a linear Paul trap. From the observed spectra, we\ndeduce final temperatures \u003c 270 mK.",
