24 October 1984 Oxide Glass Hollow Fiber For CO2 Laser Radiation Transmission
Author Affiliations +
The feasibility study of a new type of hollow-core waveguide for CO2 laser radiation guidance is described. This kind of fiber has an air core surrounded by an oxide-glass cladding which for Ary10.6 μm exibis a complex refractive index with real part <1. Curves of the measured reflectivity and real and immaginary part of the refractive index for glass samples with different PbO percentage are shown, along with attenuation measurements performed on fiber drawn from such glasses.
