Instead of gas, a fiber laser uses optical fiber made out of silica glass to get the job done. The fiber is “doped” when a rare-earth element is added to it. This level of beam is suitable for cutting a wide variety of materials, making it a stable choice over other lasers. A fiber laser can handle the bumps, knocks, vibrations, and general discord of any assembly line as well. The beam is straight and small, using precise focus and efficiency to create the mark.
Another benefit to fiber lasers are their tendency to stay safe from heat damage or fracture. This laser requires minimal maintenance for such an efficient system, making it well-suited for the construction and housing industry for laser etching leather and other materials.
