Abstract

The absolute frequency of the f-component for the UME laser was measured with the BIPM femtosecond laser comb to be (473 612 353 602.0 +/- 1.1) kHz during 3 March to 8 March, 2003 and with the UME comb to be (473 612 353 600.6 +/- 1.1) kHz from 20 June to 25 June, 2005. After appropriate correction for power and modulation shifts a subkilohertz agreement between the two measurements was found. Moreover, the relative frequency stability for different UME-BIPM laser pairs is investigated using standard heterodyne techniques and Allan variance statistics.
