摘　　要：采用掺杂粉末直拉棒工艺制备了一种小芯径的掺镱光子晶体光纤。以此光纤为增益介质,抽运波长为976 nm,实现了波长为1045 nm激光连续输出。并研究了抽运功率与光纤长度对激光性能的影响。受限于光纤的小芯径尺寸,该光纤激光器系统激光输出功率最大仅为0.42 W,激光斜率效率仅为33%。实验结果表明,利用掺杂石英粉末直拉棒工艺制备的掺镱光子晶体光纤有望应用于高功率光纤激光器的研制。A kind of Yb3＋-doped photonic crystal fiber with small core fabricated using the powder sinter direction drawn rod technology is reported. Using the Yb3＋-doped photonic crystal fiber as the laser gain medium, a fiber laser with the central wavelength of 1045 nm is obtained with the excitation of 976 nm by using the laser diode. In addition, the influence of the fiber length on the laser properties of fiber laser is experimentally investigated. The maximum output power is limited to 0.42 W by available small fiber core. The slope efficiency is 33%. The results show that the Yb3＋-doped photonic crystal fiber fabricated in the powder sinter direction drawn rod technology can be used as the potential optical material for the high power fiber laser.
