摘要:
高功率窄线宽光纤激光器在相干合成、光谱合成以及非线性频率转换等领域发挥了重要的作用，吸引了大量国内外研究人员的广泛关注。近年来，华中科技大学武汉光电国家研究中心光纤激光技术团队持续进行优秀的国产化高功率窄线宽线偏振光纤激光技术的研究工作，2022年，课题组采用基于振荡器的种子源加自研的保偏掺镱光纤先后实现单正向1.2 kW和单反向3.2 kW的线偏振窄线宽光纤激光输出。近期，课题组进一步优化保偏掺镱光纤的掺杂组分，并改良振荡器种子源设计来抑制窄线宽保偏放大过程中的TMI和受激布里渊散射（SBS）效应，最终实现了输出功率4.1 kW的窄线宽线偏振全光纤激光输出。

Abstract:High-power narrow linewidth fiber lasers have played an important role in the fields of coherent synthesis, spectral synthesis, and nonlinear frequency conversion, attracting extensive attention from domestic and foreign researchers. In recent years, the fiber laser technology group (FLTG) of Wuhan National Laboratory for Optoelectronics (WNLO) at Huazhong University of Science and Technology has been conducting excellent research on domestically manufactured high-power narrow-linewidth linearly polarized fiber laser technology. In 2022, the research team achieved a 1.2 kW narrow linewidth linearly polarized fiber laser output based on a forward-pumping structure and a 3.2 kW narrow linewidth linearly polarized fiber laser output based on a counter-pumping structure, respectively, adopting a fiber oscillator laser (FOL) seed and the homemade polarization-maintaining Yb-doped fibers (PMYDF). Recently, the research team achieved a 4.1 kW narrow linewidth linearly polarized fiber laser output by applying the combination of an optimizing doped component PMYDF and an improved FOL seed for suppressing the TMI and stimulated Brillouin scattering (SBS) effects during the power scaling.
