Abstract
We describe the traceability chain of length measurements
at Centre for Metrology and Accreditation (MIKES) from
atomic clocks to the lasers of primary interferometers.
Crucial part of the traceability chain, an optical
frequency comb generator linking optical frequencies to
atomic clocks, is described in detail. The frequency comb
generator is used in frequency calibrations of
iodine-stabilized lasers, which are operated in
compliance with the recommendations of the Practical
Realization of the Definition of the Meter. Measured
absolute frequencies of iodine-stabilized lasers, time
records of the measurements, and the respective Allan
deviations demonstrate the solid performance of the MIKES
laser frequency standards. The results are in good
agreement with the recommended values, as well as with
the independent characterizations of the measured lasers.
