Testing ultrafast mode-locking at microhertz relative optical linewidth
Michael J. Martin, Seth M. Foreman, T. R. Schibli +1
We report new limits on the phase coherence of the ultrafast mode-locking process in an octave-spanning Ti:sapphire comb. We find that the mode-locking mechanism correlates optical…
Sr lattice clock at 1x10^{-16} fractional uncertainty by remote optical evaluation with a Ca clock
A. D. Ludlow, T. Zelevinsky, G. K. Campbell +16
Optical atomic clocks promise timekeeping at the highest precision and accuracy, owing to their high operating frequencies. Rigorous evaluations of these clocks require direct comp…
Coherent optical phase transfer over a 32-km fiber with 1-s instability at
Seth M. Foreman, Andrew D. Ludlow, Marcio H. G. de Miranda +3
The phase coherence of an ultrastable optical frequency reference is fully maintained over actively stabilized fiber networks of lengths exceeding 30 km. For a 7-km link installed…
Nuclear Spin Effects in Optical Lattice Clocks
Martin M. Boyd, Tanya Zelevinsky, Andrew D. Ludlow +4
We present a detailed experimental and theoretical study of the effect of nuclear spin on the performance of optical lattice clocks. With a state-mixing theory including spin-orbit…
Sr lattice clock with inaccuracy below 10
Martin M. Boyd, Andrew D. Ludlow, Sebastian Blatt +4
Aided by ultra-high resolution spectroscopy, the overall systematic uncertainty of the - clock resonance for lattice-confined Sr has been characterized…
Compact, thermal-noise-limited optical cavity for diode laser stabilization at 1 x 10-15
A. D. Ludlow, X. Huang*, M. Notcutt +5
We demonstrate phase and frequency stabilization of a diode laser at the thermal noise limit of a passive optical cavity. The system is compact and exploits a cavity design that re…
