Advanced noise reduction techniques for ultra-low phase noise optical-to-microwave division with femtosecond fiber combs
W. Zhang, Z. Xu, M. Lours +5
We report what we believe to be the lowest phase noise optical-to-microwave frequency division using fiber-based femtosecond optical frequency combs: a residual phase noise of -120…

An Ultra-Stable Referenced Interrogation System in the Deep Ultraviolet for a Mercury Optical Lattice Clock
S. T. Dawkins, R. Chicireanu, M. Petersen +5
We have developed an ultra-stable source in the deep ultraviolet, suitable to fulfill the interrogation requirements of a future fully-operational lattice clock based on neutral me…

Sub-100 attoseconds optics-to-microwave synchronization
W. Zhang, Z. Xu, M. Lours +4
We use two fiber-based femtosecond frequency combs and a low-noise carrier suppression phase detection system to characterize the optical to microwave synchronization achievable wi…
