Abstract
We demonstrate a new, simple technique for measuring IR frequencies near 30 THz by using a femtosecond (fs) laser optical comb and sum-frequency generation. The optical frequency is directly compared with the distance between two modes of the fs laser, and the resultant beat note is used to control this distance, which depends only on the repetition rate of the fs laser. The absolute frequency of a CO2CO2 laser stabilized onto a SF6SF6 two-photon line has been measured for the first time to the authors’ knowledge. This line is an attractive alternative to the usual saturated absorption OsO4OsO4 resonances used for the stabilization of CO2CO2 lasers. First results demonstrate a fractional Allan deviation of 3×10–143×10–14 at 1 s.
