Abstract

We: are making a frequency measurement system for an optical frequency standard operating at 1.5 /spl mu/m region using a saturated absorption of the v/sub 1/+v/sub 3/ band of /sup 13/C/sub 2/H/sub 2/ molecule. After the first preliminary measurement reported at CPEM98, we have been improving the system to make it more accurate and reliable. The status report will be presented including preliminary results of the frequency measurement using a mode-locked fiber laser.
