In industry, laser cutters have been used in various areas for some time. There are different laser cutting technologies, but the basic mode of operation is pretty much the same for all of them. The laser cutter either cuts different materials or engraves a pattern on the surface. The material is vaporised or burned. This is why the process is also called thermal cutting. In order to cut or engrave with a laser, a laser beam, starting from a laser source, is bundled into a laser dot with the aid of a focusing optics at exactly the intensity required for the specific application.
