Abstract: In prospective of a new accurate determination of the Boltzmann constant by means of precise Doppler spectroscopy of Mercury atom at 253.7 nm, a primary standard traceable and ultra-stable optical reference at 1014.8 nm has been developed. Preliminary results of frequency stability performances and spectroscopic capabilities will be presented.
