Abstract
An absolute optical frequency measurement is made of the hyperfine com ponents of the 5S1/2-5D3/2 two-photon transitions in rubidium with an uncertainty of 1.3 x 10(-11). This is carried out in a simple way by t aking advantage of the near coincidence between the two-photon frequen cy at lambda=778 nm in Rb and the frequency difference of two HeNe las ers, stabilized respectively to an iodine line at lambda=633 nm and a methane transition at lambda=3.39 mum used as references. This measure ment provides a new optical frequency reference in the visible range.
