Abstract

Results of 2-year frequency comparisons of our transportable He-Ne laser standard stabilized on a component of the magnetic hyperfine structure (MHFS) of the F₂² line of methane λ=3.39 μm, with our stationary laser using resolved recoil doubler as reference are presented. The absolute frequency of the transportable laser measured at PTB (Physikalisch-Technische Bundesanstalt, Braunschweig, Germany), using the radio-optical frequency chain, was transferred to the stationary device. On the basis of the theoretical model of the line shape, the frequency of unperturbed transition has peen calculated
