    • This light is resonant with the 6 S1/2 (F=4) →6 P3/2 (F′ =4) transition and simultaneously serves to form the lattice and to depopulate the F=4 state.

    • We believe the shorter lifetime of Cs atoms to be due to the 6s→7s two-photon transition driven by the dipole trap light.

    • For a typical cloud size of σ=20 μm, we estimate the broadening caused by the field gradient B′ to be B′ σ 70 mG. The temperature broadening can be estimated as kB T/Δμ, where Δμ is the relative magnetic moment between the atom-pair state and the molecular state causing the resonance. The broadening typically varies between 50 and 200 mG.

    • We choose this two-photon transfer scheme because it is insensitive to magnetic-field fluctuations, whereas two subsequent one-photon transitions would be strongly affected.

    • A coherent transfer of Rb atoms could not be successfully implemented in our setup. We believe the magnetic gradient field in combination with the residual magnetic-field dependence of the two-photon transition to be the main reason.
