摘　　要：The optical and thermal properties of a new class of fluoroindate glass with different erbium contents were investigated via Raman,transmission,and fluorescence spectroscopies,fluorescence decay curve analysis,and differential scanning calorimetry.The strength parameters of the samples were calculated using the Judd-Ofelt theory.The mid-infrared luminescence properties of erbium-doped fluoroindate glasses were studied,and a strong emission at 2.7μm was obtained.Compared with the traditional ZBLAN glass,this glass has excellent emission properties,especially a longer fluorescence lifetime(7.09 ms)and larger emission cross-section(6.95×10^(-21) cm^(2))at 2.7μm.The results indicate that fluoroindate glass is an attractive host for mid-infrared lasers and as a gain medium for optical amplifier applications.
