    Notes: Abstract: We present a detailed description of measurements performed with a novel double optical lattice setup. In this we trap two different cesium hyperfine ground states in separate periodic potentials. A detailed account of the technical solutions and its foundations are given. We demonstrate the possibility to modulate the relative spatial position of the lattices and perform a series of systematic measurements in order to investigate the static and dynamic properties of the double optical lattice system.

    Anisotropic velocity distributions in 3D dissipative optical lattices (2003)
    Springer

    Notes: Abstract: We present a direct measurement of velocity distributions in two dimensions by using an absorption imaging technique in a 3D near resonant optical lattice. The results show a clear difference in the velocity distributions for the different directions. The experimental results are compared with a numerical 3D semi-classical Monte-Carlo simulation. The numerical simulations are in good qualitative agreement with the experimental results.

    Temperatures in 3D optical lattices influenced by neighbouring transitions (2001)
    Springer
    The European physical journal 13 (2001), S. 379-384

    Notes: Abstract: A detailed experimental study of the steady-state temperature in a 3D optical lattice for cesium has been performed for a wide range of detunings. Specifically, we have investigated the situation with the cooling and trapping light detuned far red of a ( J g↦J e = J g + 1)-transition, where the blue detuned interaction with a ( J g↦J e = J g)-transition can not be neglected. We find that the temperature scales with the optical potential due to the interaction with just the ( J g↦J e = J g + 1)-transition. This indicates that blue Sisyphus cooling has essentially no effect on the dynamics of the system, when there exists a neighbouring red detuned transition.
