The effective trapping schemes and the collection efficiency have been experimentally measured and calculated by solving an original 3D model. This model considers the whole bunch of the 32 ground and excited (P1/2 + P3/2) Zeeman sublevels, the actual trap geometry, the magnetic field intensity and direction, the light polarization, and evaluates both the velocity capture range and the number of trapped particles N. Synergetic and competition mechanisms due to the trapping and repumping lasers have been predicted and experimentally observed. The model simulation has been compared with the results reported in the literature and with those obtained by us and a quite good agreement has been found. The model can be easily adapted to the other sodium isotopes as well as to all the other alkalis.Type of Medium: Electronic ResourceURL: -

LIAD is a non-thermal phenomenon and it can be observed even with very weak light intensities. We show that the simultaneous contribution to the photo-emission of atoms adsorbed both at the film surface and within the film must be taken into account in order to fit the experimental data. We demonstrate that both the desorption efficiency and the diffusion coefficient of the alkali atoms embedded in the dielectric film depend on the desorbing light intensity. These features characterize a new class of photo-induced phenomena whose analysis gives new insights in the comprehension of the atom-surface interaction and of the atom-bulk diffusion and opens interesting perspectives for applications.Type of Medium: Electronic ResourceURL:
