How about Shanghai Feibo fiber laser?

Shanghai Feibo is a company made by the technical team of Shanghai Institute of Optics and Mechanics, and their fiber laser performance is still good. To tell the truth, they are still relatively fast on the road of localization, because as far as I know, they got the fiber grating from another industrialized company of the Institute of Optics and Mechanics: Nanjing Juke Optoelectronic Technology Co., Ltd., and some other core components are also made in China. First of all, the supply speed is definitely fast, and the later maintenance can be better.
