چکیده انگلیسی
In this paper, the properties of continuous-wave Yb-doped fiber amplifiers operating near 980â¯nm are investigated numerically. The effects of the seed light, active fiber configuration, pump power, pumping scheme and residual reflectivity of output port on performance of the 980-nm amplifier are revealed. It is found that besides the core-to-cladding ratio, both the seed power and pump power should large enough to realize the high output efficiency. It is also revealed that although the core-to-cladding ratio is important for the output power and efficiency, it only has a negligible effect on the optimum length of Yb-doped fiber. It is found that the optimum length is almost uniquely determined by the dopant concentration of Yb-doped fiber, and the plus of these two parameters are a constant almost unvaried with other parameters of Yb-doped fiber. With this result, a simple but effective method for estimating the optimum length of Yb-doped fiber is presented. Besides, it is also found that the residual reflectivity of output port should be no larger than 10â5 to optimize the output property of the 980-nm fiber amplifier. We believe that the pertinent results can provide significant guidance for deeply understanding and designing the 980-nm Yb-doped fiber amplifier.
