Polarized fiber lasers and amplifiers

High-power fiber lasers are used in industrial applications such as cutting and welding of sheet metals, e.g., in the automotive or ship building industry. The benefit of using fiber lasers lies in their ability to produce high average output powers in the 10 kW range with fundamental mode beam quality and more than 50 kW of output power with multimode beam quality with high efficiencies. Due to a robust all-fiber setup, the lasers are very rugged and can be used even in harsh production environments, where they have already demonstrated high reliability
