摘要：
New aspects of substance separation by the laser driven diffusion of gaseous mixtures through capillaries are presented. By using the chopped radiation of a low power CO2 laser, the experimental dependence of the separation coefficient on the pulse frequency in mixtures containing resonant and non-resonant gases was investigated. The induced effects agree with a model in which the number density of adsorbed molecules should be connected to temporal characteristics of the radiation. By avoiding heating effects, a pulsed laser irradiation may provide a new approach related to the practical purposes of substance separation in metal capillaries.
