Abstract

We report on recent progress in our Ramsey-Bordé interferometer with cold magnesium atoms at 457.2 nm. A resolution as high as Δν = 290 Hz was achieved, which corresponds to a quality factor of Q = 2.3×10 12. An upper limit of 170 Hz for the laser oscillator line width is inferred from the interferometric analysis of the contrast decay induced by the residual atomic motion and spontaneous emission. The performance of the spectrometer allows to realize an optical frequency standard at 457.2 nm with a short-term stability of up to σy (τ = 1s)= 8 × 10-14 with 105 atoms similar to state-of-the art, non-cryogenic microwave clocks or oscillators.
