摘要：

The frequency of a wavelength standard at 1542 nm ( 194 THz) developed in CMI for the telecommunication band C was measured with a fiber femtosecond frequency comb. The measurement was done for three transitions of acetylene (C2H2)-C-13: P( 14), P( 15) and P( 16). The results agree well with values in the recommendation for Practical realization of the definition of the metre [ 1] and even better with recent measurements made in NMIJ/ AIST [ 2,3] - the differences are lower than 2 kHz ( or 1x10(-11) rel.) for all three transitions. This agreement is significant considering the fact that the CMI laser uses an extremely simple spectroscopic arrangement and substantially lower saturation power.
