Dynamics of the light-induced atomic desorption at homogeneous illumination

An experimental investigation of Light-Induced Atomic Desorption (LIAD) at homogeneous illumination in uncoated Rb glass cell is reported. The dynamics parameters of LIAD and their dependences on the illumination intensity in uncoated cell are measured and compared with these in paraffin-coated cell and the theoretical dependences for coated cell at homogeneous illumination. The homogeneous illumination not only increases the yield of LIAD, but increases the rates of desorption and adsorption. The results are interesting for the better understanding of the process of LIAD and the atom-surface interaction, for the development of new LIAD-loaded atomic devices, all-optical control of light, optical sensors miniaturization, and new methods for surface and coating diagnostics and nanostructuring.
