Rare earth - doped heavy metal glasses (HMG) are one of the most important optical systems, which can be used for the design of solid-state laser materials and fiber light sources. Among the numerous heavy metal systems, erbium - doped lead borate glass exhibits quite large stimulated emission cross-section and broad fluorescence width at half maximum (FWHM) at 1.55 /spl mu/m band due to /sup 4/I/sub 13/2/ - /sup 4/I/sub 15/2/ transition, which is eye-safe and used for infrared optical telecommunication system. Spectroscopic properties of erbium - doped oxyfluoride lead borate glasses in multicomponent PbO - PbF/sub 2/ - B/sub 2/O/sub 3/ - Al/sub 2/O/sub 3/ - WO/sub 3/ system were investigated. The spectral linewidth analysis for main near-infrared emission spectra of the /sup 4/I/sub 13/2/ - /sup 4/I/sub 15/2/ transition and the luminescence decay curve measurements of the /sup 4/I/sub 13/2/ excited level of Er/sup 3+/ were performed.
