Show affiliationsThis second international comparison between He-Ne lasers at 543 nm exhibits similar results to the first international comparison. A standard uncertainty of 4 kHz was obtained against 2 kHz in 1993, while the average frequency difference between the lasers was −1.0 kHz against 14.2 kHz in 1993. The experimental data indicate however that a standard uncertainty below 1 kHz can be expected between two lasers. The frequency difference between the two lasers clearly lies within the limits (2.5 parts in 1011) given in the revised practical realization of the definition of the metre (1997) for the 633 nm He-Ne laser.
