摘要

在这项研究中，我们展示了一种基于激光二极管（ld）直接泵浦的高功率掺镱光纤激光器（YDFL）。串列抽运和LD直接抽运是YDFL中产生高亮度激光输出的两种常用方案。与串联泵送方案相比，LD直接泵送方案具有效率高、体积小、成本低等突出优点。因此，在工业应用方面具有显著的竞争优势。我们报道了一个20.27千瓦的单片光纤放大器，直接双波长ld反泵浦。发射波长为1080nm的光纤放大器的光对光效率为84.8%。拉曼强度比信号光强度低50 dB以上。通过优化YDF和元件的设计，可以进一步提高激光器的输出功率和光束质量。

20 kW Monolithic Fiber Amplifier With Directly Dual-Wavelength Laser Diodes Counter Pumping

In this study, we demonstrate a high-power ytterbium-doped fiber laser (YDFL) based on laser diodes (LDs) directly pumping scheme. Tandem pumping and LD direct pumping are two common schemes for generating high-brightness laser output in YDFL. Compared to tandem pumping, LD direct pumping scheme has prominent advantages such as high efficiency, small size, and low cost. Therefore, it has a significant competitive advantage in industrial applications. We report a 20.27 kW monolithic fiber amplifier with directly dual-wavelength LDs counter pumping. The fiber amplifier emitting at 1080 nm has an optical-to-optical efficiency of 84.8%. The Raman intensity is more than 50 dB lower than the signal light intensity. By optimizing the design of YDF and components, the output power and beam quality of the laser can be further enhanced.
