The aim of the study is to present the results of investigations of glasses in the system lead-bismuth-gallium-cadmium doped by Ho3+ ions. The thermal and optical properties of glasses have been determined. The structure of lead-bismuth-gallium-cadmium glasses using infrared and Raman spectroscopy methods have been determined. The investigation results have shown that the glasses are characterized by light transmittance in the range 0.5 - 7.5 μm and their refractive index equals 2,15 (4-6 μm). The results of absorption and luminescence rare earth doped glass are presented. A fiber with numerical aperture NA = 0.8 was obtained.
