We report the spectroscopic properties of Tm 3+ ‐doped and Tm 3+ /Ho 3+ ‐codoped [Ga 2 O 3 –GeO 2 –Bi 2 O 3 –PbO (PbF 2 )] glasses for S‐band optical amplifications. The Judd–Ofelt intensity parameters have been determined based on the measured absorption spectra. It is found that PbF 2 ‐modified glasses exhibit a lower Ω 2 value, and the addition of PbF 2 caused the chemical bond associated with Tm 3+ ions to be more ionic. The PbF 2 ‐free glasses have large peak emission cross‐sections in the range of 2.15–2.18 × 10 −21 cm 2 . Meanwhile, the studied glasses exhibit broad 1.47 μm emission with the full width at half‐maximum of 119–126 nm. The results indicate that these glasses are useful host material for broadband S‐band fiber amplifiers.
