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 (
)-transition, where the blue detuned
interaction with a (
)-transition can not be neglected. We find
that the temperature scales with the optical potential due to the
interaction with just the ()-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.
