Abstract

We have built an optical frequency synthesis chain starting from our laboratory-measured reference at 29 THz (CO2/OSO4 laser) to measure with a more than 10 fold improved accuracy the frequency of a He-Ne laser locked on a hyperfine transition of Iodine. The result of the measurement of the laser locked on the " f " component of (127)R11-5 transition is v = 473 612 353 586.9 ± 5 kHz. (Δv/v=l. 10-11). The uncertainty found is only limited by the reproducibility of that standard laser. Our chain is potentially capable of measuring optical frequencies from the visible to near IR range with an accuracy level of 10-12, which is presently limited by our reference accuracy.
