Paper Abstract
A high-power industrial carbon-dioxide laser with fast axial gas-flow was set up with eight radio-frequency-excited discharge tubes and four turbo-blowers. With an unstable resonator the maximum output power is 25 kW. The gas flow and the electrodes for the rf-excitation were shaped carefully to achieve homogeneous gas discharges and thus an active medium that introduces only minor aberrations into the beam of the unstable resonator. The beam propagation behavior near focus was studied for a diagnostic optics with long focal length and for processing optics with shorter focal lengths, respectively. Various welding applications in mild steel and stainless steel were carried out.
