高效率全国产化10 kW光纤激光器
Home-Made 10 kW Fiber Laser with High Efficiency
【摘要】 基于自主研发的大模场增益光纤和无源器件,采用双端抽运技术,搭建了一台全国产化10 kW光纤激光器,实现了非线性效应抑制。该激光器的功率放大器的输出功率达到10.14 kW,中心波长为1070.36 nm,3 dB光谱带宽为5.32 nm。其主放大级最大光-光转换效率为87.8%,斜率效率为89.2%,成为目前国内报道的效率最高的10 kW级光纤激光器。
【Abstract】 We propose a 10 kW fiber laser by using home-made large mode field gain fiber, passive components and dual-end-pumping technique to suppress nonlinear effects. A power amplifier with output power of 10.14 kW, wavelength of 1070.36 nm and 3 dB bandwidth of 5.32 nm is established. For the main amplification stage, the maximum optical-optical efficiency is 87.8% and the slope efficiency is up to 89.2%. To the best of our knowledge, the proposed laser is the most efficient 10 kW-level fiber laser reported in China.
