Development of IR Transmitting Chalcogenide Windows
Abstract
A quantitative study of infrared absorption in the 250-4000/cm region of As2Se3 glasses doped with small amounts of As2O3 or purified has been carried out with particular attention ot absorption in the wavelength regions of the CO2 and CO lasers. The dependence of the relative intensities of the oxide impurity bands in the 650-1340/cm region on the total amount of As2O3 added to the glass indicates the existence of three distinct oxide impurity species. A number of higher frequency impurity bands which are due to the presence of hydrogen in the glass and whose intensities are highly dependent on the glass melting conditions have been observed and classified. Intrinsic multiphonon absorption coefficients of mixed As2Se3-GeSe2 glasses were found to be of the same magnitude at the same respective frequencies as those for pure As2Se3 glass.
