Abstract
We present final results from four laser frequency comparisons involving the following He-Ne/Iodine lasers operating at wavelength (lambda) equals 633 nm: the laser RO.2 from the National Institute for Physics of Lasers, Plasma and Radiation (Romania); the laser BIPM4 from the Bureau International des Poids et Mesures (France); the laser IMGC4/5 from the Institute for Metrology `Gustavo Collonetti' (Italy); the laser INVAR3 from the Institute for Scientific Instruments (Czech Republic); the laser NMS121 from the National Standards Laboratory (Norway). We report the results coming from matrix determinations on the lines d, e, f, g and then, by reducing all mean frequency differences to the same reference laser (BIPM4), we presented them as frequency traceability of a laser through that of the reference laser.
