Nd3+-doped silica glass and fiber prepared by modified sol-gel method
文献摘要：
Large-size Al3+/Nd3+co-doped silica glass with 5000 ppm Nd3+and 50,000 ppm Al3+doping concentrations was prepared by the modified sol-gel method combined with high-temperature melting and molding technology.Electron probe micro-analyzer tests indicated that high doping homogeneity was achieved with this sample preparation method.The spectral properties of the Nd3+ions were evaluated.Nd3+-doped silica fiber[NDF]with a core-to-clad ratio of 20/125 μm was drawn from the preform with the Al3+/Nd3+co-doped silica glass as the core.In the laser oscillation experiment,a maximum output power of 14.6 W at 1.06 μm with a slope efficiency of 39.6％was obtained from the NDF pumped by a commercial 808 nm laser diode.To the best of our knowledge,this is the highest laser power reported for an NDF operated at 1060 nm and prepared by a non-chemical vapor deposition method.In the master oscillator power amplifier experiment,a maximum power of 16.6 W corresponding to a slope efficiency of 30.5％at 1061 nm was also demonstrated.The laser performance of the NDF exhibited the great advantages and potential of the modified sol-gel method in fabricating Nd3+-doped silica glass for a new type of NDFs like large mode area fibers and fibers with large diameter ratio of core/cladding.
