Query: Phase stability transfer across the optical domain using a commercial
  optical frequency comb system   We report the frequency noise suppression of a 674nm diode laser by
phase-locking it to a 1560nm cavity-stabilized laser, using a commercial
optical frequency comb. By phase-locking the frequency comb to the narrow
reference at telecom wavelength we were able to phase-coherently distribute the
reference stability across the optical spectrum. Subsequently, we used one of
the comb teeth as an optical reference for a 674nm external cavity diode laser.
We demonstrated the locked 674nm laser frequency stability by comparing it to
an independent cavity-stabilized laser of the same wavelength and by performing
spectroscopic measurements on a dipole-forbidden narrow optical transition in a
single $^{88}$Sr$^+$ ion. These measurements indicated a fast laser linewidth
of 19Hz and 16Hz, respectively.
