Abstrakt: The stability and efficiency of a 3.5 μm erbium-doped fluoride fiber is strongly limited by the core pumping setup of a 1976 nm pump. A dual-wavelength-clad-pumped scheme was put forward for a more robust and higher electro-optical efficiency in this paper, and a numerical model was built up to stimulate the fiber. Parameter optimizations were given for both the traditional dual-wavelength pump setup and our new scheme. The results show the possibility of using a laser diode as pump source for the generation of a 3.5 μm laser, and the characteristics were analyzed. [ABSTRACT FROM AUTHOR]
