The following article comes from Changfei Guangfang, author EVERFOTON
1- Vertically integrated fiber laser industry chain
EVERFOTON has vertically integrated the fiber laser industry chain. In December 2021, EVERFOTON will inject all fiber laser-related basic materials, special fibers, and laser device businesses into EVERFOTON Guangfang. In April 2022, Nanjing Guangfang Technology Co., Ltd. was merged into EVERFOTON and became a wholly-owned subsidiary of EVERFOTON Guangfang. Nanjing Guangfang Technology Co., Ltd. has been deeply involved in the field of fiber lasers for many years, and has many top talents and core technologies in the fields of semiconductor laser chips, pump sources and fiber lasers. YOFC will continue to create high-quality and differentiated fiber laser solutions for global users through the vertical integration of the entire industry chain.
2-Technical advantages of the whole industry chain
EVERFOTON has an advanced R&D and manufacturing platform for the entire fiber laser industry chain and many key core technologies.
Key technology: high power active fiber
After more than ten years of technology accumulation, EVERFOTON's rare earth doping technology has reached the international leading level. In 2018, it took the lead in developing three-cladding active optical fibers in China, and has the large-scale production capacity of double-cladding and three-cladding active optical fibers. The output power of active fiber continues to increase. At present, the stable output power of a single fiber of ytterbium-doped fiber is as high as 6kW, leading the technological development of the industry.
Key technology: full range of passive optical fibers
With the PCVD platform and technical advantages accumulated for more than 30 years, EVERFOTON has built a laser passive fiber manufacturing platform with the largest production capacity, perfect technology and products in China, and realized the large-scale production of a full range of fiber laser passive fiber products. In recent years, YOFC has rapidly launched ring fiber, homogenized fiber, super-large core diameter fiber, polarization-maintaining passive fiber, etc. A number of new products fully demonstrate the technical advantages of the PCVD platform and EVERFOTON's rapid response and customization capabilities for industrial applications.
Key technologies: core devices such as pump source and high-power grating
EVERFOTON has mastered the key technologies of pump packaging, grating, beam combiner, QBH and other core laser devices and components, laying a solid foundation for high-quality, high-performance fiber lasers.
The pump source is designed with advanced design to achieve lightweight and miniaturized high power output, and an automated production platform has been built.
Build an automated UV write grating and ultra-fast femtosecond write grating platform, and launched a variety of high-reliability grating products such as the highest single-cavity 5kW-class high-power grating, high-power femtosecond grating, Raman suppression grating, and various types of gratings customized development capabilities.

3-High-quality, differentiated fiber laser solutions
EVERFOTON's vertical integration advantages of the entire industry chain and leading technical strength ensure the high quality of fiber lasers and enable EVERFOTON to provide differentiated and customized fiber laser solutions, including a variety of options Wavelength, different beam modes, and diversified fiber laser solutions such as quasi-continuous, narrow linewidth, and ultra-short pulses.
EVERFOTON has maintained its leadership in the miniaturization, light weight and portability of lasers, and has developed 500W portable air-cooled high-brightness lasers weighing only 10kg, as well as air-cooled kilowatt-class backpack-type laser handheld welding machines suitable for outdoor applications. Quantitative, easy-to-carry products.
At present, EVERFOTON has formed a series of fiber laser solutions with power ranging from 100 watts to 10,000 watts, covering sheet metal cutting, new energy battery welding, metal 3D printing, laser cladding, laser cleaning and many other segments.
In the future, EVERFOTON will give full play to the advantages of vertical integration of the entire industry chain, create high-quality, differentiated and intelligent laser application solutions with ingenuity, and devote itself to benefiting people's lives with leading optical technology.
