Two-photon rubidium clock detecting 776~nm fluorescence
River Beard, Kyle W. Martin, John D. Elgin +2
The optical atomic clock based on the two-photon transition in rubidium is a candidate for a next generation, manufacturable, portable clock that fi…
Distributed Coherent Beamforming at 60 GHz Enabled by Optically-Established Coherence
Drake Silbernagel, Yu Rong, Isabella Lenz +10
We implement and experimentally demonstrate a 60 GHz distributed system leveraging an optical time synchronization system that provides precise time and frequency alignment between…
Development of a High-Doppler Shift Optical Simulator to Test Femtosecond-Level Optical Time-Frequency Transfer
Matthew S. Bigelow, Kyle W. Martin, Nolan Matthews +5
We have developed an optical simulator to test optical two-way time-frequency transfer (O-TWTFT) at the femtosecond level capable of simulating relative motion between two linked o…
Demonstration of Real-Time Precision Optical Time Synchronization in a True Three-Node Architecture
Kyle W. Martin, Nader Zaki, Matthew S. Bigelow +4
Multi-node optical clock networks will enable future studies of fundamental physics and enable applications in quantum and classical communications as well as navigation and geodes…
Demonstration of a Mobile Optical Clock Ensemble at Sea
A. P. Hilton, R. F. Offer, E. Klantsataya +14
Atomic clocks are at the leading edge of accuracy and precision and are essential for synchronization of distributed critical infrastructure, position, navigation and timing, and s…
