高功率光纤激光器与传统固体激光器相比具有转换效率高、光束质量好、散热方便等优势,是国际上激光技术领域的研究热点。近几年来,随着单纤输出功率的不断攀升,高功率光纤激光器的应用前景日益看好。高性能双包层光纤一直是制约我国高功率光纤激光研究发展的瓶颈之一。近一年来
Compared with traditional solid-state lasers, high-power fiber lasers have the advantages of high conversion efficiency, good beam quality and convenient heat dissipation, which are the hot topics in the field of laser technology in the world. In recent years, with the single-fiber output power rising, the application prospect of high-power fiber lasers is increasingly optimistic. High-performance double-clad fiber has been one of the bottlenecks restricting the development of high-power fiber laser in our country. In the past year
