The laser spectroscopy is a fundamental approach for the realisation of traceable optical frequency standards.
In the 1:55 m wavelength band, widely used in telecommunications, the acetylene is the typical and the most
widespread absorption media. We present our investigation of using the hydrogen cyanide (HCN) as a cost-
e cient and readily available alternative, that also provides a wider frequency span (from 1527nm to 1563 nm).
We have compared the practical aspects of using new absorption media in comparison to existing experience
with the acetylene with an outlook to carry out an independent measurement of the entire spectra. The results
should contribute to the future inclusion of the HCN spectroscopic data into the Mise en pratique, thus allowing
for the use of HCN as a reference for the realisation of traceable laser standards.
