THE REALIZATION OF THE DEFINITION OF THE METRE AT INRIM

M. Zucco, M. Bisi, P. Cordiale
Abstract:
In this paper we present the traceability chain for the calibration of the frequency of laser standards that realize the definition of the metre at the National Institute of Metrological Research (INRIM) in Italy in accordance with the mise en pratique issued by the CIPM. We describe the way our femtosecond laser frequency combs are referenced to the SI second and the new research activity on the production and testing of iodine cells.
