Abstract

The IR spectra of As2Se3 glass samples containing known amounts of oxygen (4 × 10-3 to 7.7 × 10-2 wt %) or carbon (≤5.8 × 10-3 wt %) are measured, and the parameters of impurity-related absorption bands and extinction coefficients are determined. The effects of oxygen, carbon, sulfur, and hydrogen on the transmission of As2Se3 glass are analyzed. At an oxygen content on the order of 10-5 wt %, this impurity causes optical losses in the range 900–1100 cm-1 comparable to the intrinsic losses. The permissible carbon content of As2Se3 glass is 10-6 to 10-5 wt %. Carbon inclusions 0.07 µm in diameter cause optical losses comparable to the intrinsic losses in the spectral window of As2Se3 glass when present in a concentration of ∼104 cm-3.
