Abstract： A 0 . 2 % （mass fraction） high concentration ion doped chalcogenide glass was prepared for gain fibers used in 4 μm wavelength fiber lasers，and a single-mode double cladding gain fiber was fabricatedusing rod-in-tube technology.Theoptical propertiesof theglassand fiberpreparedunderdiferent processes werecomparedandanalyzed byusing X-ray diffraction，diffrential scanningcalorimetry，electron probe element analysis，ellpsometer，infraredthrmalimager，infraredmicroscopy，nfraredFouriertranformspectrometerflu rescence spectrometer，and other methods.The substrate lossof the final preparedoptical fiber is about2.65 dB / m ， and strong fluorescence emission at 3.8-4.8 μ m was successfully detected.This chalcogenide glass fiber has relatively high solubility，good thermal stability and emission property，which has the potential to serve asa gain medium for4 μmband fiber lasers.
