我们评估了包层泵浦光纤激光器的不同功率限制。尽管泵浦源最近取得了进展，但它们仍然主要受到可用泵浦功率的限制。我们发现单模掺镱光纤激光器的输出功率应该可以达到超过 1 kW。实验上，我们实现了在1080 nm处输出功率为272 W、M2值为3.2的掺镱光纤激光器，以及在1565 nm处输出功率为103 W、M2值为2.0的铒镱共掺光纤激光器。我们相信这些是迄今为止报道的功率最高的镱和铒-镱光纤激光器。
We assess different power limits of cladding-pumped fiber lasers. Despite recent advances in pump sources, these are still primarily limited by available pump power. We find that it should be possible to reach output powers beyond 1 kW in single-mode ytterbium doped fiber lasers. Experimentally, we have realized an ytterbium-doped fiber laser with 272 W of output power at 1080 nm, with an M2-value of 3.2, as well as an erbium-ytterbium co-doped fiber laser with 103 W of output power at 1565 nm, with an M2-value of 2.0. We believe these are the highest-power ytterbium and erbium-ytterbium fiber lasers ever reported.
