Jiang Honggu first introduced the current status of the laser equipment industry and the major overseas suppliers. China's laser fiber industry has been monopolized by OFS, Nufern, nLight, FiberCore and other European and American developed countries for a long time. In recent years, in the context of the Made in China 2025 strategy, China's traditional industrial manufacturing industry is facing a deep transformation, and the laser industry has ushered in new development opportunities. According to the data displayed on the scene, whether in terms of the market size of laser equipment , the shipment volume of fiber lasers, or the market size of China's direct semiconductor lasers, the development of the laser industry is very considerable. Step forward.

Regarding the types of laser fiber, Jiang Honggu made a detailed introduction and sharing to the audience. There are three main types of laser fiber, including large mode field fiber, pump energy fiber (pure quartz core double-clad fiber) and laser energy fiber (pure quartz core triple-clad fiber). Among them, the large-mode-field fiber includes two types of erbium-doped large-mode-field active fiber and germanium-doped large-mode-field passive fiber. Pure quartz core double-clad fiber and pure quartz core triple-clad fiber are relatively mature laser fibers. The acrylate coating and nylon tight cladding are added to the two, which can improve the strength of the fiber, enhance stability and practicality. Has a significant effect. According to Jiang Honggu, these advanced optical fibers have basically been domestically produced.

The main points of laser fiber production technology mainly include preform technology (including preform core rod MCVD deposition technology, Yb immersion solution formulation and immersion technology, preform sleeve technology and rod wall octagon processing), drawing technology (including mature Drawing process of octagonal optical fiber, self-developed and improved drawing coating technology, coating coating technology, ETFE and NYLON's tight-packed fiber extrusion technology. Jiang Honggu said that as domestic enterprises continue to increase research and development and improve fiber performance Develop new products. At present, domestic optical fibers can replace imported products in terms of physical and optical performance.

In the speech, Jiang Honggu also introduced the performance of the laser fiber from the aspects of anti-aging, bending resistance, power, optical application and gain of the coating. After the wonderful speech, the speakers interacted with the audience frequently, and the atmosphere of the event was warm. In the Q & A session, Jiang Honggu answered questions from the audience on the autonomy of the production of the first photonic coating technology and the development plan of Yb fiber. He said that at this stage, the company's coating materials are mainly sourced from abroad, and it will definitely strengthen the development of independent coating technologies in the future to meet the rapid development of the laser industry and the higher requirements for laser fiber technology.
