A laser cutter that cuts sheet metal can transform a sheet of paper in seconds. You can also do the same with a laser tube cutter machine but it is a completely different story about how it is done.
Some things can be quite obvious. The fiber laser "generator", as it is called, is smaller than traditional CO2 resonators. The fiber laser is actually created by banks and modules of diodes. They can be assembled into a compact module with a power range of 600 to 1,500 watts. A number of modules are combined to make the final powered receiver, which is often the size of small filing cabinets. The light is amplified and channeled through fiber-optic cabling. The fiber-optic cable transmits the light exactly as it was before. This ensures that there is no loss of quality or power. Then, it is adjusted and focused according to the material being cut.
