Abstract

The tellurium halide based glass fibers, the TeX glass fibers, have a wide range of IR transmission. The minimum attenuation of about 0.5 dB/m is located in the wavelength region of 7-9.5 micrometers . Fibers having a core-clad structure have been developed. The diameter of the fibers can change from about 50 micrometers to 700 micrometers depending on the applications. These fibers are very stable in water and in normal air condition. The minimum bending radius for a fiber with a diameter of 200 micrometers is less than 1 cm. the maximum working temperature is 120 degree(s)C. A tunable CO₂ laser with a maximum output power of 7 W is used for the power delivery experiments. The used TeX glass fibers have a diameter of about 600 micrometers and a length of about 1 meter. The two ends of the fiber are just cleaved without polishing. The relationship between output and input power has been established at different wavelengths. More than 206 W has been obtained through a TeX glass fiber at the wavelength of 9.3 micrometers corresponding to the strong absorption of dental tissues.
