Fiber Laser Ideas
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.
Fiber lasers only have a narrow focal point so it is difficult to use them for cutting thick materials. A CO2 laser would be the best choice.
