中文摘要：
实现了一个窄线宽36pm的Er：Yb共掺硅基光纤激光器，输出中心波长是1569．4nm.激光器的谐振腔是由一个高反的Bragg光纤光栅和另一端光纤端面4％的菲涅尔反射组成．用3．8m长的Er：Yb共掺光纤，在975m的LD激光器泵浦下，获得了最大输出功率达到6W，斜率效率达到23．5％，在输出功率范围内有明显的功率饱和现象．
英文摘要：
A Er.Yb co-doped silica fiber laser source operating at 1 569. 4 nm is reported, with a very narrow 36 pm linewidth laser output. Up to 6 W CW laser power is obtained from an 3.8 m-long Er. Yb co-doped silica fiber, which is cladding-pumped by a 975 nm diode laser. The fiber laser cavity included a high reflective fiber Bragg grating and the other fiber end Fresnel 4% reflection. The slope efficiency is 23. 5%, and there is obvious power saturation under high power pumping.
