Abstract

The world´s most powerful laser system for industrial applications would be presented. Ytterbium fiber laser combines record 101.3 kW output power, CW operational mode and an excellent beam quality. Beam parameter product (BPP) does not exceed 16 mm × mrad, when we use 300 μm × 10 m feeding fiber, or near 25 mm × mrad, when fiber-to-fiber output coupler with 500 μm × 50 m process fiber is used. Emission wavelength is 1070 nm. High wall-plug efficiency 35.4%, compact laser cabinet and total weight less than 3600 kg open the new opportunities in different industrial and mobile applications.
