Abstract

In the contribution, a 5.58 kW monochromatic narrow linewidth fiber laser centered at 1080 nm realized by combining house-made confined doped fiber and bidirectional pump scheme has been presented. At the maximum power of 5.58 kW, the beam quality factor M² is ∼1.5. Experimental results have revealed that 90% confined doping is competent to increase TMI threshold by 20% and fit well with numerical calculation, which proves confined doping has the potential for further power scaling of narrow linewidth fiber laser by TMI mitigation, and experimental results indicate that confined doping can also be regarded as a reference for the design and optimization of high-power narrow linewidth near-diffraction-limited fiber lasers.

基于国产受限掺光纤的5.58 kW窄线宽光纤激光器

在贡献中，提出了将自制的受限掺杂光纤与双向泵浦方案相结合，实现了以1080 nm为中心的5.58 kW单色窄线宽光纤激光器。在最大功率为5.58 kW时，光束质量因子M2为~ 1.5。实验结果表明，90%受限掺杂能使TMI阈值提高20%，与数值计算吻合良好，证明了受限掺杂对窄线宽光纤激光器的TMI抑制具有进一步放大功率的潜力，实验结果也可作为高功率窄线宽近衍射极限光纤激光器设计和优化的参考。

期刊介绍： The Journal of Lightwave Technology is comprised of original contributions, both regular papers and letters, covering work in all aspects of optical guided-wave science, technology, and engineering. Manuscripts are solicited which report original theoretical and/or experimental results which advance the technological base of guided-wave technology. Tutorial and review papers are by invitation only. Topics of interest include the following: fiber and cable technologies, active and passive guided-wave componentry (light sources, detectors, repeaters, switches, fiber sensors, etc.); integrated optics and optoelectronics; and systems, subsystems, new applications and unique field trials. System oriented manuscripts should be concerned with systems which perform a function not previously available, out-perform previously established systems, or represent enhancements in the state of the art in general.
