Domestic fiber lasers have performed well in recent years, but most of them are concentrated in the medium and low power fields.
According to relevant statistics, domestic fiber lasers account for more than 92% of shipments of small and medium power.
In terms of high-power applications, foreign companies still dominate.
Although domestic companies have made great progress by relying on the localization of pump source packaging, pump combiners, energy combiners, isolators, fiber gratings, laser transmission components and other devices, and have gradually moved away from the Reliance on foreign enterprises, but there is still a big gap in the technology and quality of some key components, such as pump source chips, matched large mode field double-clad passive optical fiber and large mode field double-clad ytterbium-doped fiber at full power None of them have achieved domestic mass production.
At present, most fiber laser manufacturers use imported large double-clad ytterbium-doped optical fiber and match the same imported double-clad passive optical fiber, which shows that the core raw materials of fiber lasers have not been localized.
At the same time, strict verification standards and ultra-long verification cycles have further caused the iterative improvement of optical fiber products for lasers to lag behind.
It can be seen that the localization of double-clad ytterbium-doped optical fiber and double-clad passive optical fiber is an important reason restricting the development of domestic fiber lasers.
Therefore, the task of localization is crucial and cannot be delayed.
Thanks to the rapid development and gradual maturity of the material processing industry, industrial lasers continue to grow in the global laser market share. Among them, fiber lasers perform particularly well, and the domestic fiber laser market is also growing rapidly.
According to statistics, domestic fiber laser production capacity reached 74,000 units in 2016, mainly composed of nearly 60,000 low-power fiber lasers, 12,000 medium-power fiber lasers, and more than 2,000 high-power fiber lasers.
In fiber laser systems, the gradual maturity and advancement of active optical fibers, passive optical fibers, laser diodes, and various optical fiber devices have led to tremendous development of fiber lasers and amplifiers.
Based on double-clad ytterbium-doped fiber, especially large mode field double-clad ytterbium-doped fiber (LMA DC-YDF) and matching large mode field double-clad passive fiber (LMA DC-GDF) Performance characteristics, fiber lasers show the advantages of high output power (high peak, average power), excellent beam quality, integration, and low cost.
