, We have checked that the difference in the light shifts undergone by the two involved transitions, which induces an inhomogeneous broadening of the two-photon resonance

, For the discretizations we used the following parameters. The thickness of the sublayers in each period is ?z = 24 nm, the sampling interval for the longitudinal density distribution along the lattice axis is 100 ?m, it is 7.5 ?m for the transverse distribution of the probe-beam intensity and of the atomic sample

, When we vary the lattice wavelength, we change the beam power accordingly in order to keep the same trapping depth and thus the same atom number and temperature

, Note that, in this case, the extrapolation length is not directly proportional to the mean-free path, it is bounded by the radius of the sphere. Finally, the extrapolation length should also depend on the gain or absorption coefficient, the diffusion approximation, one obtains z 0 2?3l sc , whereas the exact result for a semi-infinite slab is z 0 ? 0.71l sc
