Comparison of two Strontium optical lattice clocks in agreement at the 10−16 level
Two optical lattice clocks operated on the transition 1S0-3P0 of the 87Sr atom are now operational at the LNE-SYRTE laboratory, their comparison aims at demonstrating that no systematic effect has been overlooked in their respective accuracy budgets. In this proceeding we focus only on trapping effects, we discuss technical aspects of the calibration of the lattice induced light shifts, and we show the observation of the second order light shift. Data resulting from the comparisons are reported and discussed.
