The dynamics of Light-Induced Atomic Desorption (LIAD) in 6 cells with different coatings (PDMS coated cells prepared with two different concentrations of PDMS in ether, SC-77, PCHS, DCDMS, OTS) is investigated. The rates of desorption and adsorption of the Rb atoms when the illuminating light is switched ON and OFF and their dependence on the illuminating blue-light power are measured. The influence of the homogeneity of illumination for increasing the desorption and adsorption rates is evaluated. The results are interesting for the better understanding of LIAD and its dynamics and for the development of new optoelectronic elements, LIAD-loaded atomic devices and their miniaturization, and new methods for surface and coating diagnostics.
