Strontium optical lattice clocks at LNE-SYRTE

In optical lattice clocks, a large number of neutral atoms confined in an optical lattice are probed by a narrow linewidth laser. These clocks combine an excellent control of the systematic effects, while offering a record stability thanks to the large number of interrogated atoms. Here, we report on recent results obtained with two strontium optical lattice clocks at LNE-SYRTE, Observatoire de Paris.
