IntroductionThe series of ring spot fiber lasers developed by UW Laser are primarily designed for the new energy battery and 3C industries. They combine the high brightness advantage of single-mode fiber lasers with the beam distribution advantage of ring spot fiber lasers, making them well-suited for precision and high-speed welding applications of high-reflectivity materials. These lasers can effectively suppress spatter, thereby improving welding quality and yield rate. The series offers a maximum total output power of 6000W and allows flexible adjustment of the output beam mode. It can achieve various combinations of central and ring beam powers, such as 2kW+2kW, 4kW+2kW, and lower configurations, with both central and ring powers being adjustable. Equipped with UW's patented negative feedback power adjustment technology, it can increase the full-power lifespan of the laser by more than 20%. In addition, it can also achieve special fiber outputs in various specifications such as 34/102μm, 50/150μm, 50/600μm, 100/300μm, 100/600μm and so on.
