Query: Tailored design of mode-locking dynamics for low-noise frequency comb
  generation   We report on a mode-locked laser design using Yb-doped fiber lasers for
low-noise frequency-comb generation. The frequency comb covers the spectral
range from $700$ to $1400$ nm. Although this range is more practical for many
measurements than that produced by the more commonly used Er-fiber lasers, it
has been addressed in only a handful of reports, mainly due to the difficulty
of generating a fully coherent supercontinuum at $1\;\mu$m. We overcome this
difficulty by a tailored design of the mode-locking dynamics that succeeds in
generating energetic 33 fs-long pulses without even using higher-order
dispersion compensation, while ensuring that the laser operates with net zero
cavity dispersion for low-noise supercontinuum generation. After locking to a
Cs atomic clock, this frequency comb is used for absolute-frequency
measurements of a Nd:YAG-I$_2$ laser to verify its accuracy by comparison with
results from the International Committee for Weights and Measures. After this
verification, it is further used to measure the absolute frequency of a 543-nm
two-mode stabilized He-Ne laser, which is routinely used for length
measurements in our institute, thus verifying its practical utility in
metrology applications. The entire setup is built with readily available
components for easy duplication by other researchers.
