Description
Summary:This article deals with sulfur and selenium-based glasses doped with rare earth ions. It reviews the most significant glass compositions and their related thermal and mechanical properties, with emphasis given to optical and spectroscopic properties in the infrared domain. Optical transparency, multiphonon relaxations, luminescence in optical fibers and planar waveguides doped with trivalent rare earth ions are presented in details. Applications as new compact light sources and lasers, especially for the mid-IR domain, are shown. •The paper reviews the luminescence of rare earth-doped chalcogenides.•Laser and optical amplification are reviewed in near-infrared spectral range.•Emissions from 3 to 5 μm are reviewed in sulfide and selenide glasses.•Lasing at wavelengths beyond 5 μm is reviewed with Tb3+ ions or Ce3+-doped fibers.•Luminescence was observed at 7–8 μm in selenide fiber doped with Sm3+, Tb3+, Dy3+.
