Accurate laser frequency locking to optical frequency combs under low-signal-to-noise-ratio conditions
C. Guo, M. Favier, N. Galland +7
We demonstrate a method for accurately locking the frequency of a continuous-wave laser to an optical frequency comb in conditions where the signal-to-noise ratio is low, too low t…

Search for transient variations of the fine structure constant and dark matter using fiber-linked optical atomic clocks
B. M. Roberts, P. Delva, A. Al-Masoudi +51
We search for transient variations of the fine structure constant using data from a European network of fiber-linked optical atomic clocks. By searching for coherent variations in…
