摘　　要：对光纤预制棒制备过程中沉积的气体流量、管内压强等参数和光纤掺杂组分进行了研究.研究发现通过共掺其他元素,可以使掺镱光纤的荧光谱发生移动.基于此,制备了有利于1018nm激光输出的掺镱双包层光纤.在增益光纤长度为7m时,实现了22.8W的1018nm激光输出,光-光效率接近70%,并且没有观察到明显的自发辐射和饱和现象.The effects of codopants and the deposition parameters such as gas flowrate and pressure in tube during the fabrication of fiber performs are studied. It is found that the fluorescence spectrum of Yb3＋ can shift when codoping other elements, according to which, a double cladding Yb3＋-doped fiber that is beneficial for 1018 nm laser is fabricated for the first time. When the fiber length is 7 m, an output of 22.8 W at 1018 nm is obtained. The optical-optical conversion efficiency is approximately 70%, and there are neither spontaneous radiation nor saturation.
