Laser fiber is the forefront of technology research and development in the field of special fiber, which fully reflects the company’s technical strength and industry voice. Dr. Chen Wei, Chief Engineer of Hengtong Optical Fiber, introduced that, unlike traditional optical fibers, the double-clad erbium-doped fiber DC-YDF released this time is highly targeted in fields of application, mainly for laser marking, material processing, medical green laser pointer and other fields . At the same time, in terms of performance, erbium-doped fiber not only transmits light, but also generates and amplifies light. It is an active fiber and an active fiber.
Traditional fiber is simply transmitted, it is a passive fiber and passive fiber. Chen Wei said that the double-clad erbium-doped laser fiber is currently the core component of fiber lasers and amplifiers. Its manufacturing technology is difficult, the production process is complex, and the added value of the product is high. Heavy troops line up in order to win the commanding heights of the technology.
This product adopts the world’s most advanced rare earth chelate gas phase doping technology and combined with MCVD rod technology, which realizes that the deposition tube can be completed in one step without disassembly. It has the advantages of short rod production time and less process pollution. Conducive to uniform dispersion of doped ions. In addition, the product’s rare-earth chelate vapor-phase doping technology truly realizes in-situ deposition, simple operation, good repeatability, and can deposit large-sized erbium-doped mandrels, thereby preparing large-sized preforms by matching the quartz cladding. The output and batch consistency of the green laser pointers of the optical fiber are well ensured, so that a kilowatt-level laser fiber is manufactured, and the major demand for a kilowatt-level active fiber in the field of energy optoelectronics is solved.
