Original abstract
The definition of both meter and second relies on precisely measured frequency. The convenient sources of such frequencies are lasers stabilized by molecular vapours. The He-Ne lasers stabilized by iodine vapours represent the cornerstone sources in the visible spectrum. On the other hand, the infrared spectrum (particularly 1550 nm C-band) is of metrological interest thanks to its cost-effective, readily available components. The widely used absorption media at 1550nm has been two acetylene isotopes ((C2H2)-C-12, (C2H2)-C-13), while (HCN)-C-13-N-14 represents an alternative covering a broader spectrum well corresponding to the telecommunication C-band.
