Dark-resonance Doppler cooling and high fluorescence in trapped Ca-43 ions at intermediate magnetic field

Dark-resonance Doppler cooling and high fluorescence in trapped Ca-43 ions at intermediate magnetic field

We demonstrate simple and robust methods for Doppler cooling and obtaining high fluorescence from trapped ^43 Ca ^+ ions at a magnetic field of 146 Gauss. This field gives access to a magnetic-field-independent ‘atomic clock’ qubit transition within the ground level hyperfine structure of the ion, b...
