Abstract

A ytterbium ion standard is currently under development at JPL for both ground and space applications. We have chosen the ytterbium ion for its large hyperfine splitting of 12.6 GHz, and accessibility of its first excited electronic energy levels with light from frequency-doubled semiconductor and solid state lasers. Performing microwave-optical double resonance spectroscopy we have achieved 25 mHz Ramsey fringes with a signal-to-noise ratio better than 350:1 in the shot noise limit, which corresponds to an inferred stability on the order of 1.8×10 ^-14/√(τ)
