“…As, Ge, Se, Te. Optical fibres formed from these materials [3] can be assembled into multi-fibre bundles. However, their optical attenuation at 10.6pm due to impurity and multi-phonon absorptions is likely to displace their initial applications to shorter wavelengths (i.e.…”

Glasses based on germanium dioxide have been prepared and their bulk optical constants measured in the wavelength range 5-55 mu m. These data have been applied to assess the potential of the glasses as hollow waveguides for the CO2 laser operating at about 10.6 mu m wavelength. The results suggest that glasses with low oxide additions (<10 mol.%) to GeO2 are preferable when waveguide transmissions and fibre fabrications are taken into account. Some initial data on waveguide bending losses indicate that these are reduced significantly when the glass maintains a refractive index of less than unity at CO2 laser wavelengths.

The strengths of as‐drawn, abraded, and pristine Se, As2Se3, As2S3, and Ge30As15Se55 fibers are reported. Pristine strength values range from an average of 80 MPa for Se and Ge30As15Se55 to 100 and 180 MPa for As2Se3 and As2S3, respectively. Although these values are considerably higher than those reported previously for bulk samples, in no case does the maximum observed strength reach more than about 6% of that expected from simple theoretial calculations. Several factors that can control the strength are discussed. The overall behavior is interpreted in terms of the glass structures which permit localized stress relaxation effects in regions of weak, nondirectional bonds. These effects occur at temperatures well below the glass‐transition region.
