拉制了两种低损耗、单模、近红外宽带传输的空芯反谐振光纤,并用于高功率超短皮秒脉冲传输。利用无节点结构的空芯反谐振光纤实现了平均功率为74 W、单脉冲能量为185μJ、峰值功率为10.8 MW的超短脉冲传输,且输出激光在频域和时域上均没有发生明显变化。 Two types of air-core anti-resonant fiber with low loss, single-mode and near-infrared broadband transmission were fabricated and used for high-power ultra-short picosecond pulse transmission. The short-pulse transmission with an average power of 74 W, a single pulse energy of 185 μJ, and a peak power of 10.8 MW was realized by using a hollow fiber anti-resonant fiber without node structure and the output laser did not change significantly in the frequency and time domains .
