Providing 1E-16 short-term stability of a 1.5 μm laser to optical clocks
C. Hagemann, C. Grebing, T. Kessler +5
We report on transferring 1E-16-level fractional frequency stability of a "master laser" operated at 1.5 μm to a "slave laser" operated at 698 nm, using a femtosecond fiber comb as…
Long-distance remote comparison of ultrastable optical frequencies with 1e-15 instability in fractions of a second
Andre Pape, Osama Terra, Jan Friebe +8
We demonstrate a fully optical, long-distance remote comparison of independent ultrastable optical frequencies reaching a short term stability that is superior to any reported remo…
Optical frequency synthesis and measurement using fibre-based femtosecond lasers
Gesine Grosche, Burghard Lipphardt, Harald Schnatz
We report the synthesis and measurement of an ultra-precise and extremely stable optical frequency in the telecommunications window around 1543 nm. Using a fibre-based femtosecond…
Ultra-precise measurement of optical frequency ratios
Jörn Stenger, Harald Schnatz, Christian Tamm +1
We developed a novel technique for frequency measurement and synthesis, based on the operation of a femtosecond comb generator as transfer oscillator. The technique can be used to…
