摘要
基于自主研制的均匀掺杂低热光系数25/400μm掺镱双包层光纤,开展了全光纤高功率窄线宽光纤激光放大实验。激光系统实现了中心波长为1060.3 nm、线宽为25 GHz、最高功率为2.2 kW的单模激光输出,其斜率效率达78%,光束质量因子M^2≈1.2,其功率是目前报道的基于国产25/400μm掺镱双包层光纤窄线宽放大器单模激光输出的最高功率。
Based on the self-developed large mode area Yb-doped double-cladding 25/400 μm active fiber with uniform doping and low thermo-optic coefficient, an all-fiber high-power narrow-linewidth fiber laser amplification experiment was carried out. The laser system achieves a single-mode fiber laser output with a maximum power of 2.2 kW, a linewidth of 25 GHz, and a center wavelength of 1060.3 nm, with a slope efficiency of 78% and a beam quality factor of M^2≈1.2. This is the highest output power currently reported for narrow-linewidth single-mode amplifiers based on domestic Yb-doped double-cladding 25/400 μm active fiber, to the best of our knowledge.
