A clock network for geodesy and fundamental science
C. Lisdat, G. Grosche, N. Quintin +32
Leveraging the unrivaled performance of optical clocks in applications in fundamental physics beyond the standard model, in geo-sciences, and in astronomy requires comparing the fr…
Characterization of a 450-km Baseline GPS Carrier-Phase Link using an Optical Fiber Link
Stefan Droste, Christian Grebing, Julia Leute +6
A GPS carrier-phase frequency transfer link along a baseline of 450 km has been established and is characterized by comparing it to a phase-stabilized optical fiber link of 920 km…
8E-17 fractional laser frequency instability with a long room-temperature cavity
Sebastian Häfner, Stephan Falke, Christian Grebing +5
We present a laser system based on a 48 cm long optical glass resonator. The large size requires a sophisticated thermal control and optimized mounting design. A self balancing mou…
