中文摘要：
采用四氯化硅水解掺杂结合高频等离子体粉末熔融法制备了掺Yb^3＋石英玻璃,以此玻璃作为光纤纤芯,通过堆积-拉丝法拉制了掺Yb^3＋大模场微结构光纤。光纤的纤芯直径达到了130μm,并且研究了光纤的吸收光谱、发射光谱、损耗特性和激光特性。以此光纤为增益介质,当泵浦波长为970nm时,实现了波长为1 033nm的连续激光输出,激光输出的最大功率为3.6 W以及激光斜率效率为42.1%。测试结果表明,利用水解工艺制备的掺Yb^3＋大模场微结构光纤有望应用于高功率光纤激光器的研制。
英文摘要：
The Yb^3＋-doped silica glass has been prepared by the SiCl4 hydrolysis doping and powder melting technology based on high frequency plasma.The large-mode-area microstructure fiber（MSF）is fabricated by stack-drawing technology with the Yb^3＋-doped silica glass as the fiber core.The core diameter of the fiber is about 130μm,and the absorption spectrum,emission spectrum,loss characteristics as well as laser characteristics are studied.Using the Yb^3＋-doped microstructure fiber as the laser gain medium,a fiber laser with the central wavelength of 1 033 nm is obtained with the excitation wavelength of 970 nm by using the laser diode.The maximum output power of the laser is 3.6W,and the laser slope efficiency is 42.1%.The test results indicate that the Yb~（3＋）-doped microstructure fiber fabricated by the hydrolysis process can be used as the potential laser material for the high power fiber laser.
