Brillouin amplification in phase coherent transfer of optical frequencies over 480 km fiber
O. Terra, G. Grosche, H. Schnatz
We describe the use of fiber Brillouin amplification (FBA) for the coherent transmission of optical frequencies over a 480 km long optical fiber link. FBA uses the transmission fib…
Phase- coherent comparison of two optical frequency standards over 146 km using a telecommunication fiber link
Osama Terra, Gesine Grosche, Katharina Predehl +5
We have explored the performance of two "dark fibers" of a commercial telecommunication fiber link for a remote comparison of optical clocks. The two fibers, linking the Leibniz Un…
Optical frequency transfer via 146 km fiber link with 10^{-19} relative accuracy
G. Grosche, O. Terra, K. Predehl +5
We demonstrate the long-distance transmission of an ultra-stable optical frequency derived directly from a state-of-the-art optical frequency standard. Using an active stabilizatio…
Laboratory Limits on Temporal Variations of Fundamental Constants: An Update
E. Peik, B. Lipphardt, H. Schnatz +3
Precision comparisons of different atomic frequency standards over a period of a few years can be used for a sensitive search for temporal variations of fundamental constants. We p…
