In this paper, laser emission at 3.92 μm in heavily-holmium-doped fluoride fibers using 888 nm and 1660 as pumping sources is investigated through numerical modeling. The dual-wavelength system has lower threshold higher slope efficiency than the single-wavelength nm. addition, can decrease heat load due to input influencing energy transfer up-conversion cross-relaxation processes effectively, which indicates possibility of raising heat-damage providing high-power generation. This research...
We report a double-cladding fluoroindate fiber with three layers of step refractive index glass. The gain is fabricated by the traditional rob-in-tube method. It possesses tunable from 1.46 to 1.51 via modification glass components. good thermal-mechanical performance protects against thermal damage. luminescence characteristics and radiation parameters are studied, results indicate enhanced emission higher Er3+ doping concentration. maximum output power slope efficiency heavily erbium-doped...
