Abstract :
An international comparison of two independent absolute optical frequency measurements between NMIJ/AIST, Japan and JILA, USA has been made using a portable Nd:YAG laser. The agreement between the two measurements is 330/spl plusmn/380 Hz, yielding a measurement uncertainty of 6.7/spl times/10/sup -13/ that is mainly contributed from the reproducibility of the portable laser. This comparison is used to confirm the measured absolute frequency of NMIJ-Y3, which is reported to the Consultative Committee for Length (CCL) for the determination of the frequency value of iodine-stabilized Nd:YAG lasers.
