SL series fiber lasers are completely researched and produced by Our Company. solving the bottleneck problems such as pump power stripping and heat dissipation system stability and fast response, increased the 14/250 or 20/400 fiber output from 500w to 2000W. The fiber laser combines high average power, high reliability and high electro-optical conversion efficiency, and can be widely used in laser cutting ,cladding, welding and other occasions. Especially in the welding of thin metal plates, not only the welding speed is fast, but also the weld seam of the plates is uniform, which is obviously compared with other similar lasers on the market.
