Fiber lasers have proven to be the most efficient laser cutting method. Their flexibility enables cutting of a wide range of materials—from steel to aluminum to non-metal materials such as plastics, glass, etc.—of different thicknesses. The fiber laser cutting process also results in a high-quality cutting edge. High-power CW fiber lasers are commonly used for industrial applications: as the power output increases, the cutting speed and the ability to process thicker materials improve, making them ideal for high-volume production.
