Lattice-induced photon scattering in an optical lattice clock

We investigate scattering of lattice laser radiation in a strontium optical lattice clock and its implications for operating clocks at interrogation times up to several tens of seconds. Rayleigh scattering does not cause significant decoherence of the atomic superposition state near a magic wavelength. Among the Raman scattering processes, lattice-induced decay of the excited state (5s5p)\,{}^{3}\mathrm{P}_{0}to the ground state...
