Abstract

The action of CO₂ laser (power density of 10³ - 10⁶ W/cm²) on silicates has been investigated. Spectroscopic, chemical and x-ray 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-O groups take place.
