Abstract :
In this paper, we report on the metrological capabilities of CO/sub 2//OsO/sub 4/ optical frequency standards operating around 29 THz. Those frequency standards are currently involved in various fields, such as frequency metrology, high resolution spectroscopy, and Rydberg constant measurements. The most impressive features of the standards lies in the 10/sup -15/ level frequency stability allied to a long-term reproducibility (1 yr) of 1.3/spl times/10/sup -13/.
