Abstract

Lasers from two national metrological institutes (NMIs) were compared in 2015 as part of the CCL-K11 ongoing key comparison, initiated by the 13th meeting of the Comité Consultative des Longuers (CCL) in 2007. The absolute frequency of R(127) 11-5 transitions of molecular iodine was measured for these lasers following the technical protocol for CCL-K11. The results of these measurements are compiled in the present report. The comparison reports, as communicated by each participant, are included as appendices.

This document constitutes the seventh final report for the ongoing key comparison CCL-K11.
