The 87-Sr optical frequency standard at PTB
St. Falke, H. Schnatz, J. S. R. Vellore Winfred +8
With 87-Sr atoms confined in a one dimensional optical lattice, the frequency of the optical clock transition 5s^2 ^1S_0 - 5s5p ^3P_0 has been determined to be 429 228 004 229 872.…
Tackling the blackbody shift in a strontium optical lattice clock
Thomas Middelmann, Christian Lisdat, Stephan Falke +3
A major obstacle for optical clocks is the frequency shift due to black body radiation. We discuss how one can tackle this problem in an optical lattice clock; in our case 87-Sr: f…
Collisional losses, decoherence, and frequency shifts in optical lattice clocks with bosons
Ch. Lisdat, J. S. R. Vellore Winfred, T. Middelmann +2
We have quantified collisional losses, decoherence and the collision shift in a one-dimensional optical lattice clock with bosonic 88Sr. The lattice clock is referenced to the high…
Interrogation laser for a strontium lattice clock
T. Legero, Ch. Lisdat, J. S. R. Vellore Winfred +4
We report on the setup and characterization of a 698 nm master-slave diode laser system to probe the 1S0-3P0 clock transition of strontium atoms confined in a one-dimensional optic…
