Some things are obvious. A fiber laser has a smaller laser "generator" than a CO2-resonator. Actually, the fiber laser is made by banks of diodes which are combined in a small module. These modules can have a power range from 600 to 1,500 W. To create the final powered resonance, multiple modules are spliced together. This is usually the same size as a small filing cupboard. The fiber-optic cables channel the light and amplify it. Fiber-optic cables transmit the same light as when they were generated, with no loss of power and quality. The fiber-optic cable is then adjusted and focused to cut the appropriate material.
Some things are very obvious. A fiber laser's laser generator is smaller than a CO2 resonator. The fiber laser is actually made from banks of diodes, which are assembled in a module the size of a briefcase. It can produce power from 600 to 1,500 Watts. The final powered resonator is made up of multiple modules that are connected together. It can be as small as a small filing cabinet. Fiber-optic cable amplifies the light produced and channels it. The light that exits the fiber optic cable is exactly the same as it was when it was generated. There is no loss in power or quality. The light is then focused and adjusted to determine the material that will be cut.
