Impurity absorption by chalcogenide glasses in CO laser emission region
Abstract
The mechanism governing the high optical losses in chalcogenide glasses in the region of CO laser radiation (5 to 6 microns) is determined by investigating laboratory and commercial specimens of arsenic trisulfide and arsenic triselinide glasses, as well as commercial IKS series glasses. In examining the transmission spectra of various chalcogenide glasses, high nonselective absorption is noted in the emission region of CO lasers. This absorption occurs on impurities, which can be seen in As2S3 by ordinary microscopy, and in As2Se3 and IKS-29 by infrared microscopy. Atomary carbon and silicon dioxide are felt to determine the high level of optical losses in the frequency range in question.
