Saturated Spectroscopy of HCN

This work brings the preliminary results of saturated absorption spectroscopy of Hydrogen Cyanide gas (H13C14N), a promising optical frequency reference medium for telecommunication C-band wavelengths. We optimized the experimental system based on parameters for detection of the selected hyperfine transition in low pressure H13C14N absorption cell and observed and investigated the unwanted effect of degradation of the saturated spectroscopy signal due to H13C14N molecules permanent dipole moment.
