Paper Abstract

An experimental setup for precision processing of composite materials based on nanosecond pulsed and continuous ytterbium fiber lasers with a wavelength of 1.06 μm and a radiation power up to 1 kW with an optical scanning systems based on galvanic drives with a beam velocity of up to 17 m/s has been developed. The setup provides a power density in a focused light spot with a diameter of ≃100 μm using a continuous laser of 107 W/cm2 and a pulsed laser of 109 W/cm2, which is one order of magnitude higher than the threshold values necessary for removing carbon fiber in the evaporation mode. The focus depth of the focused radiation allows for high-quality processing of sheet blanks.
