摘要：
In this paper, a hundred -watt -level near -diffraction -limited step -index Yb-doped fiber (YDF) laser near 980 nm is demonstrated firstly, to the best of our knowledge. By using the 11.7-W 979-nm single -mode seed light, the in -band amplified spontaneous emission (ASE) is well suppressed and the maximum output power of 101.5 W with the beam quality (M 2 factor) of 1.285 was obtained. This work does not only propose an effective method for the suppression of in -band ASE, but also provides a cost-effective solution of hundred -Watt -level near -diffraction -limited fiber lasers near 980 nm.
