This is a thermal cutting process for processing sheet metal. The laser beam is created by the laser source, conducted by a transport fiber or mirrors in the machine cutting head where a lens focuses it at very high power on a very small diameter. This focused laser beam meets the sheet metal and melts it.
The laser beam is created by an active fiber and transmitted over a transport fiber to the machine cutting head. Fiber lasers are significantly smaller than CO₂ lasers and generate twice as much power from the same amount of current. A fiber cutting system is primarily suited for processing thin to medium-thick sheet metal. It also cuts non-ferrous metals (copper and brass).
