How much does a good laser cutter cost
You should be aware that the fiber laser will have limitations on the size of your work area and the materials you can cut.
An optical fiber laser bends the light by refraction. An optical fiber cable transmits light through an impure transparent silica core. The core is then covered with cladding. This is another layer of silica, doped with additional materials to lower its refractive index. Due to their differing refractive indexes, light will be refracted at the core-clad interface.
