A strontium optical lattice clock with $1 \times 1 0^{- 17}$ uncertainty and measurement of its absolute frequency

Richard Hobson, William Bowden, Alissa Silva +5

We present a measurement of the absolute frequency of the 5s $^{2}$ $^{1}$ S $_{0}$ to 5s5p $^{3}$ P $_{0}$ transition in $^{87}$ Sr, which is a secondary representation of the SI second. We descr…

A mid-infrared magneto-optical trap of metastable strontium for an optical lattice clock

Richard Hobson, William Bowden, Alvise Vianello +2

We report on the realization of a magneto-optical trap (MOT) for metastable strontium operating on the 2.92 $μ$ m transition between the energy levels $5 s 5 p^{3} P_{2}$ and $5s4…
