RESUMO

We present a new class of heavy metals fluoride glasses (HMF) of InSrBaZnGdNa and InSrBaZnGaNa compositions. We have realized a study of the physical properties such as refraction index, characteristic temperatures, stability and optical properties such as absorption, emission, lifetime of pure, Nd or Pr doped glasses. These properties are similar to those obtained for glasses of ZrBaLaAlNa (ZBLAN) composition. The main characteristic of pure indium fluoride glasses is their larger transmission window in the infrared region (8330 nm) compared to ZBLAN composition (6650 nm). Rare earth doped glasses are promising materials for the development of glasses laser with emission in the 1050-1320 nm range (Nd) and 1320 nm (Pr), as well as optical amplifiers for telecommunication in the optical window centered at 1300 nm, as prominent emission bands are located at 1315 nm (InSBZnGdN), 1317 nm (InSBZnGdN:Nd) and 1320 nm (InSBZnGdN:Pr).
