Direct comparisons of European primary and secondary frequency standards via satellite techniques
F. Riedel, A. Al-Masoudi, E. Benkler +46
We carried out a 26-day comparison of five simultaneously operated optical clocks and six atomic fountain clocks located at INRIM, LNE-SYRTE, NPL and PTB by using two satellite-bas…
1.5 m lasers with sub 10 mHz linewidth
D. G. Matei, T. Legero, S. Häfner +8
We report on two ultrastable lasers each stabilized to independent silicon Fabry-Pérot cavities operated at 124 K. The fractional frequency instability of each laser is completely…
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…
