Abstract
As2Se3.4 glass samples with controlled oxygen content in the range (1.4-7.9 ) X 10(-2) wt % were used to assess the effect of oxygen impurity on the IR absorption spectrum of the class. The spectral dependence of the extinctio n coefficient for oxygen impurity was determined in the range 600-1400 cm(- 1). It was shown that the presence of 10(-5) wt % O gives rise to additiona l losses comparable to the intrinsic losses in the CO2 lasing range.
