Laser control of the diffusive flow of gases into vacuum through obstacles with a developed surface
Abstract
The possibility of using lasers for controlling molecular gas flows through diffusion obstacles is investigated experimentally using Br2, C6H5-CH3, and SF6 molecules and argon, CO, and CO2 lasers, respectively. It is shown that the diffusive flow into vacuum of the molecules of a surface-sorbed gas through fine porous membranes with relatively scarce narrow through channels can be selectively controlled by a laser in the case where the gas is resonant with the laser emission. The effect can be used for the separation of compounds and isotopes.
