Laser-induced selective sublimation from silicates

摘要

Abstract: The action of CO$-2$/ laser (power density of 10$+3$/ $MIN 10$+6$/ W/cm$+2$/) on silicates has been investigated. Spectroscopic and chemical analysis of sublimates and irradiated zone made it possible to establish that by laser action on these matters the selective excitation of localized vibrational mode up to breaking of covalent bonds with the selective sublimation of Si-0 groups take place. !2
