光纤激光是继气体激光、化学激光和固体激光之后的新一代激光技术,是近年来世界各国科学研究的热点领域。制约光纤激光功率提升的主要技术瓶颈是系统集成技术和光纤材料制备技术。目前,我国科研工作者成功掌握了千瓦级光纤激光系统集成技术并实现了产业化,但是所用的光纤激光材料与核心器件还严重依赖进口。相较于比较成熟的系统集成技术,我国光纤激光材料的科学研究和产业化进程相对滞后,尚无法提供成
Fiber laser is a new generation of laser technology after gas laser, chemical laser and solid laser. It is a hot field of scientific research all over the world in recent years. The main technical bottleneck restricting the power of fiber laser is system integration technology and optical fiber material preparation technology. At present, our country’s scientific research workers have successfully mastered the integrated technology of the kilowatt-class fiber laser system and realized the industrialization, but the fiber laser materials and core components used are still heavily dependent on imports. Compared to the more mature system integration technology, China’s fiber laser material science and industrialization process is relatively lagging, still can not provide into
