Final report for the period 2007-2009 on the CCL-K11 ongoing key comparison

Lasers from nine national metrology institutes (NMIs) were compared as part of the CCL-K11 ongoing key comparison, initiated by the 13th meeting of the Comite Consultative des Longeurs (CCL) in 2007. The absolute frequency of the f component of the R(127) 11 - 5 transition of molecular iodine was me...

Description
Summary:Lasers from nine national metrology institutes (NMIs) were compared as part of the CCL-K11 ongoing key comparison, initiated by the 13th meeting of the Comite Consultative des Longeurs (CCL) in 2007. The absolute frequency of the f component of the R(127) 11 - 5 transition 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. [PUBLICATION ABSTRACT]
