“…The maximum output power of the laser was 109 W, with a slope efficiency of 13% corresponding to the total pump power. The M 2 factor was about 1.9 at the maximum output power [47]. The above studies imply that the single-mode 100 W-level fiber laser near 980 nm should be possible by optimizing the design of the DCYF.…”

“…After that, by improving the suppression of optical feedback and the ability of the cladding light stripper (CLS), the output power was further increased to 50.8 W with a slope efficiency of 15.6%, while the beam quality was worsened to 2.5 M 2 factor, because of the higher gain of the higher-order transverse modes (HOMs) [46]. In 2022, a 100 W-level fiber laser near 980 nm was demonstrated with the same fiber by using the master oscillator power amplifier (MOPA) configuration [47]. The maximum output power of the laser was 109 W, with a slope efficiency of 13% corresponding to the total pump power.…”

“…Currently, the output power is limited to a level of tens-of-Watts with an M 2 factor smaller than 1.5. This can be limited to 100 W with an M 2 factor of about 2 by optimizing the DCYF [47]. The pertinent slope efficiency generally ranges from 10% to 30% with respect to the launched pump power.…”

In this paper, the development of a high-power continuous wave (CW) fiber laser near 980 nm is reviewed. This review is focused primary on the power evolution resulting from the designation of Yb-doped fibers, which is important in the suppression of the amplified spontaneous emission (ASE) around 1030 nm. Current studies on the in-band ASE as the power limitation of the Yb-doped fiber lasers near 980 nm are also summarized in this review.

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 (M2 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.
