International comparisons of He-Ne lasers stabilized with¹²⁷I₂at = 633 nm (July 1997). Part VIII: Comparison of NIM (China), NRLM (Japan), KRISS (Republic of Korea) and BIPM lasers at = 633 nm

Abstract

This paper reports the eighth set of results of a series of grouped laser comparisons from national laboratories undertaken by the Bureau International des Poids et Mesures (BIPM) at the request of the Comité Consultatif pour la Définition du Mètre (CCDM, now the Consultative Committee for Length, CCL) during the periods July 1993 to September 1995 and March 1997 to July 1997. This comparison, like the previous seven, is expected to be listed as a key comparison in the context of the ongoing BIPM.L-K10 series.
