High power Fiber Lasers are made of active optical fiber and semiconductor laser diodes – a combination of two of the most innovative and advanced laser technologies. These lasers use diodes as a light source for pumping the active fiber. The laser beam is generated in the optical fiber and is transmitted by flexible armored cable. Special active fibers are doped with rare-earth ions, allowing extremely powerful generation of very small core, which makes it possible to produce a kilowatt power lasers with excellent beam quality. „IPG “uses a lot of proprietary technology to create arguably the best kilowatts” Fiber “lasers available on the market today.
