What is the difference between diode laser and fiber laser
Plasma can cut almost any material that is conductive. Laser machines are unable to cut reflective metals like brass, copper, and aluminum.
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.
