We demonstrate frequency-comb-based optical two-way time-frequency transfer across a three-node clock network. A fielded, bidirectional relay node connects laboratory-based master and end nodes, allowing the network to span 28 km of turbulent outdoor

We use frequency-comb-based optical two-way time-frequency transfer (O-TWTFT) to measure the optical frequency ratio of state-of-the-art ytterbium and strontium optical atomic clocks separated by a 1.5-km open-air link. Our free-space measurement is

Frequency-comb-based optical two-way time and frequency transfer (O-TWTFT) can support future ultra-precise clock networks over free-space links. However, demonstrations have thus far only operated at one corner of a complex parameter space, which ba

We demonstrate optical two-way time-frequency transfer (O-TWTFT) across a three-node free-space network. The network spans 28 km of outdoor air and relays time and frequency from a master node, through an intermediate fielded node, to an end node. De

Optical two-way time-frequency transfer, based on the exchange of frequency comb pulses, can support femtosecond-level time transfer and 10-18-level frequency comparison. Here, we present recent results with a focus on the impact of atmospheric turbu

We demonstrate optical frequency comparison of the 171Yb, 27Al+ and 87Sr atomic clocks with measurement uncertainties below 1 part in 1017, and discuss how phase-coherent and synchronous clock comparisons can be used to improve measurement stability.

We measure optical timing jitter due to atmospheric turbulence using frequency comb lasers. Retrieving the refractive index structure parameter, Cn2, from this data, we find windspeed- dependent agreement to Cn2 values derived from in situ instrument

We characterize the impact of turbulence on optical pulse timing jitter over a uniform, near-ground path and compare the results with theory. Use of frequency combs enabled phase- continuous measurements down to 200-fs over multiple hours.

Comb-based O-TWTFT provides exemplary performance in transferring precision timing over km-scale turbulent atmospheric paths. However, its performance through strong turbulence is not fully understood. Here we investigate transient timing deviations
