Experimental study of the laser control of the diffusion of molecular bromium through barriers with fine pores
Abstract
An argon laser (lambda = 514 nm) was used in a study of the laser control of bromium-molecule diffusion through finely porous glass. The effect of laser radiation on the diffusion flux of bromium molecules was studied in the range between 0.1 and 100 mg/h sq cm. Results indicate that the diffusion control involves the polarizational effect of the radiation on resonant molecules on the surface. It is concluded that finely porous membranes can be effectively used for the selective laser control of gas flows.
