Abstract

The change in infrared reflection spectra of natural silicates caused by CO₂ laser action on the surface of these matters has been investigated. The matters mentioned above have intensive inhomogeneously broadened infrared absorbtion band of assymmetric valent Si-O-Si vibrations at the range of laser action, that provide intensive absorbtion of laser energy. The laser action on these matters lead to the intensive sublimation of matter with torch formation at the irradiated surface.
