Stability of the proton-to-electron mass ratio
Alexander Shelkovnikov, Robert James Butcher, Christian Chardonnet +1
We report a limit on the fractional temporal variation of the proton-to-electron mass ratio as, obtained by comparing the frequency of a rovibrational transition in SF6 with the fu…

Absolute frequency measurement of an SF6 two-photon line using a femtosecond optical comb and sum-frequency generation
Anne Amy-Klein, Andrei Goncharov, Mickael Guinet +4
We demonstrate a new simple technique to measure IR frequencies near 30 THz using a femtosecond (fs) laser optical comb and sum-frequency generation. The optical frequency is direc…
