摘要
基于溶胶凝胶技术结合高温烧结法,制备了折射率起伏小于1.5×10^-4的Yb-Al-P-F高浓度掺杂石英芯棒,采用堆垛法制备了纤芯数值孔径仅为0.02的75μm芯径的光子晶体光纤。采用80cm长的该型光纤在主振荡功率放大器皮秒放大结构中实现了平均功率102W的激光输出,峰值功率超过1MW,且66min内未观察到功率下降。这是目前国内报道的国产光纤应用于高亮度皮秒放大系统实现峰值功率最高的自研光子晶体光纤。
Based on the sol-gel technology combined with high temperature sintering, the Yb-Al-P-F high concentration co-doped silica glass rod with refractive index fluctuation less than 1.5×10^-4 was prepared. Using the rod as the core, a photonic crystal fiber with a core diameter of 75 μm and a core numerical aperture of 0.02 was fabricated by the stack-and-draw technique. Using this fiber of 80 cm in length, an average output power of 102 W and a peak power over 1 MW were achieved in a master oscillating power amplification picosecond pulse system, and no obvious power decay was observed within 66 min. To our best knowledge, this is the best self-made photonic crystal fiber applied in the high-brightness picosecond amplification system, which can obtain the highest peak power in China.
