    We fabricated an ytterbium-doped phosphorus-low aluminophosphosilicate ternary laser fiber. Owing to photodark-ening and mode instability, the fiber-based kW-level laser setup showed obvious degradation of laser power and slope efficiency as compared to that with cladding-power-stripper-free.

    Thermal properties of luminescence in bismuth/erbium co-doped optical fibre (BEDF) have been investigated. In particular, the fluorescence intensity ratio (FIR) characteristics with regard to Er3+ and aluminum-related bismuth active center (BAC-Al) is studied. Similar thermal characteristics of FIR to that reported in erbium-doped optical fibre (EDF) is observed. The results demonstrate that BEDF may also be used for FIR related temperature sensing applications. © 2018 IEEE.

    Temperature dependence of cutoff wavelength of Bi/Er co-doped fiber (BEDF) is investigated. In temperature range from 23°C to 500°C, effective cutoff wavelength of BEDF is found to be a linear function of temperature, shifting from 912 nm to 946 nm at a rate of ∼ 76 pm/°C. The difference of thermal expansion coefficient (TEC) between core and cladding is believed to be the dominant factor leading to the observed phenomenon. © 2018 IEEE.
