  • Abstract
    We demonstrate the reduction of residual Doppler shifts for a laser-cooled neutral atom optical frequency standard to near negligible levels through use of second-stage laser cooling and atom interferometry. For the NIST Ca optical clock, this opens up the possibility for uncertainties of less than 1 part in 1016
