FCA series air-cooled continuous-wave fiber laser is developed and produced by Reci Laser. Compared with traditional gas and solid-state lasers, it has the characteristics of high electro-optic conversion efficiency and superior beam quality. At the same time, the structure of fiber laser is more compact because of the coilability of fiber. This series can be widely used in metal welding, cutting, industrial processing, military defense and scientific research with the advantages of high electro-optic conversion efficiency, high output power, high beam quality, compact structure, maintenance free and low cost.
