High Power High Quality Double Clad Yb-Doped Fiber Optic

High-power and high-quality double-clad ytterbium-doped fiber  is the core gain medium of modern fiber lasers and amplifiers, and it is a key technology for achieving high-brightness and high-efficiency laser output. Into it through in the fiber core of rare earth elements in “yb” , and adopt unique of double package layer structure, leading the laser technology of the innovation.

Its core advantages and introduction are as follows:

Outstanding power expansion capability: Traditional single-mode fibers are limited by nonlinear effects and thermal management issues. The double-cladding structure encloses the single-mode fiber core (for conducting signal light) within a multi-mode inner cladding (for conducting pump light), significantly increasing the absorption area and length of the pump light. This design enables the optical fiber to efficiently convert several kilowatts or even tens of thousands of watts of pump light into laser output, easily breaking through the kilowatt power mark.
 

Extremely high output beam quality: Despite the extremely high power, the laser is ultimately output from the central single-mode fiber core. This ensures that the laser has excellent beam quality and high brightness. This high-brightness beam can be focused to an extremely small spot in industrial cutting, welding and other applications, thereby achieving precise processing effects and extremely high energy density.

Outstanding energy conversion efficiency: The ytterbium ion has a simple energy level structure and high quantum efficiency, with a wide absorption range for pump light, and is particularly suitable for being pumped by high-power multimode laser diodes. Combined with a high-quality double-cladding design, the pump light is fully absorbed and utilized, and the overall photoelectric conversion efficiency of the machine can exceed 30%, significantly reducing operating costs and system heat load.

Excellent thermal management and reliability: high-quality optical fibers adopt precise optical fiber design and manufacturing processes, ensuring excellent doping uniformity and extremely low background loss. This not only reduces heat generation but also enhances the fiber’s anti-dimming ability at high power, ensuring the long-term stability and extremely long service life of the laser in harsh industrial environments.

In conclusion, high-power and high-quality double-clad ytterbium-doped fiber is the cornerstone driving the development of the next generation of high-power fiber lasers. With its comprehensive advantages of high power, high brightness, high efficiency and high reliability, it is widely used in industrial manufacturing, national defense research, medical equipment and other fields.
