Cold Beam Optical Clock with Multifrequency Spectroscopy
William G. Tobias, Bryan Hemingway, Steven Peil
We demonstrate an optical clock based on Ramsey-Bordé interferometry in a laser-cooled Ca beam. The mean velocity is reduced by an order of magnitude relative to a therma…

Progress on Optical Clock Technology for Operational Timescales
S. Peil, W. Tobias, J. Whalen +2
While optical clock technology has advanced rapidly in recent years, incorporating the technology into operational timescales has progressed more slowly. The highest accuracy frequ…
