  • Abstract
    Recent advances concerning two-photon Ramsey fringes in SF6 at 30 THz obtained with a 1 m separation between the two interaction zones are presented. The experiment is referenced to a primary standard, the Hydrogen maser / Cs fountain located at BNM-SYRTE, Observatoire de Paris, via a femtosecond laser frequency comb generator. This results in an absolute frequency measurement of the central fringe to plusmn1.4 Hz which corresponds to 5times10-14 in relative frequency.
