Spectroscopy using tunable diode lasers is an area of research that has gone through a
dramatic evolution over the last few years, principally because of new exciting approaches …

Ultracold Yb+ 174 ions and Ca 40 atoms are confined in a hybrid trap. The charge exchange
chemical reaction rate constant between these two species is measured and found to be 4 …

Individual electrodynamically trapped and laser cooled ions are addressed in frequency
space using radio-frequency radiation in the presence of a static magnetic field gradient. In …

Trapped ions are a leading system for realizing quantum information processing (QIP). Most
of the technologies required for implementing large-scale trapped-ion QIP have been …

Absorption imaging has played a key role in the advancement of science from van
Leeuwenhoek's discovery of red blood cells to modern observations of dust clouds in stellar …

We present the design and operation of an ytterbium ion trap experiment with a setup
offering versatile optical access and 90 electrical interconnects that can host advanced …

We observed elastic collisions between laser-cooled fermionic lithium atoms and calcium
ions at the energy range from 100 mK to 3 K. Lithium atoms in an optical-dipole trap were …

Chip-based, single-frequency and low phase-noise integrated photonic laser diodes
emitting in the violet (412? nm) and blue (461? nm) regime are demonstrated. The GaN …

We present and analyze two pathways to produce commercial optical-fiber patch cords with
stable long-term transmission in the ultraviolet (UV) at powers up to~ 200 mW, and typical …

We produce large numbers of low-energy ions by photoionization of laser-cooled atoms
inside a surface-electrode-based Paul trap. The isotope-selective trap's loading rate of 4× 10 …
