  "abstract": "We report a comprehensive spectroscopic investigation of dysprosium (Dy³⁺)-doped fluoroindate (InF₃-based) glasses as a promising material platform for mid-infrared fiber lasers. Dy³⁺ ions exhibit a stimulated emission cross-section of 0.31 × 10⁻²⁰ cm² at 2924 nm for the ⁶H₁₃/₂ → ⁶H₁₅/₂ transition, with a gain bandwidth of >500 nm. The associated Stokes multiphonon emission sideband further extends the emission up to at least 4 µm. Transition probabilities of Dy³⁺ ions are analyzed using a modified Judd-Ofelt formalism incorporating configuration interaction effects. Concentration quenching of the ⁶H₁₃/₂ excited-state lifetime is characterized, and anomalously strong multiphonon nonradiative relaxation is discussed. These properties are evaluated in comparison with other low-phonon-energy host matrices for Dy³⁺ doping. Energy transfer processes in Er³⁺,Dy³⁺ codoped glasses are quantified. Laser action is demonstrated in a bulk Er³⁺,Dy³⁺:InF₃-based glass, with free-running emission spanning 2.7–3.4 µm, and, in addition, a double-clad fiber laser diode-pumped at 976 nm delivers output power at the 100 mW level at 3.3 µm. InF₃-based glass fibers with optimized codoping concentrations emerge as promising candidates for broadly wavelength-tunable and ultrashort-pulse mid-infrared laser sources.",
