| 1 | Effective suppression of the photodarkening effect in high-power Yb-doped fiber amplifiers by H2 loading显示文摘The radical suppression of the photodarkening effect and laser performance deterioration via H2 loading were demonstrated in high-power Yb-doped fiber(YDF)amplifiers.The photodarkening loss at equilibrium was114.4 d B/m at 702 nm in the pristine fiber,while it vanished in the H2-loaded fiber.To obtain a deeper understanding of the impact of photodarkening on laser properties,the evolution of the mode instability threshold and output power in fiber amplifiers was investigated.After pumping for 300 min,the mode instability threshold of the pristine fiber dropped from 770 to 612 W,and the periodic fluctuation of the output power became intense,finally reaching 100 W.To address the detrimental effects originating from photodarkening,H2 loading was applied in contrast experiments.The output power remained stable,and no sign of mode instability was observed in the H2-loaded fiber.Moreover,the transmittance at 638 nm confirmed the absence of the photodarkening effect.The results pave the way for the further development of high-power fiber lasers. | RUITING CAO GUI CHEN YISHA CHEN ZHILUN ZHANG XIANFENG LIN BIN DAI LUYUN YANG JINYAN LI | 2020 | Photonics Research2020，8，3： | 2 |

| 3 | Research on the implementation of West Africa-North Africa grid interconnection using new electricity-water composite transmission technology显示文摘Combining the characteristics of the reverse distribution of solar resources and water resources in North Africa,West Africa and the Sahara,this paper proposes the West Africa-North Africa grid interconnection project to realize the optimal configuration of desert solar resources and surrounding water resources,and introduce the water resources of West Africa's Niger River and North Africa's desalinated seawater to improve the living environment and development conditions in the hinterland of the Sahara Desert;build photovoltaic bases along the route to send clean electricity to North Africa and West Africa.This paper studies the transmission channel path,electricity-water composite transmission technology and project scheme,and analyzes the economics of the project and the water supply and demand conditions of the Niger River.The research results show that it is feasible in hydrological characteristics to lead the Niger River water along the power transmission channel that crosses the Sahara Desert,and the new electricity-water composite transmission technology has obvious economic advantages. | Yu Zhang Jinyu Xiao Zhou Zhou Yun Zhao Haibin Wan Yisha Lin | 2021 | Global Energy Interconnection2021，4，5： | 0 |
