分析了1.48微米泵浦的Er/SuP3+/掺杂光纤的增益特性与光纤结构的关系。从理论和实验上推导出了最佳的V值。对于阶跃折射率光纤，最佳V值为1.6，小于最小化光斑尺寸所需的V值。V值较小的光纤具有较大的Er/SuP3+/限制效应。对于激光二极管泵浦，在1.536微米处获得了1.7dB/mW的效率，并描述了其弯曲特性。>；
The fiber-structure dependence of the gain characteristics of Er/sup 3+/ doped fibers pumped at 1.48 mu m is analyzed. The optimum V value is derived theoretically and experimentally. For step-index fibers, the optimum V value is 1.6, which is smaller than that needed to minimize spot size. The fiber with a small V value enjoys a large Er/sup 3+/ confinement effect. For laser diode pumping, an efficiency of 1.7 dB/mW is achieved at 1.536 mu m. The bending characteristics are also described. >
