Paper Abstract

Radio frequency excited fast-axial-flow CO2-lasers in the power range between 2.5 and 5.0 kWatts offer new possibilities in material processing, because of their excellent mode structure, low divergence and good pulsing capability. Due to the minimum required maintenance, they are specially suitable for industrial use. The welding properties of these lasers are characterized by a high depth to width ratio (up to 7:1) and fast welding speed, achieved by electron beam welding. Because of their' good mode structure and excellent pulsing capability (up to 20 kHz) these lasers can also be used for cutting.
