Generation and Application of a Pulsed CO2 Laser of High Average Power
Pulsed CO2-lasers with high repetition rate and high average power are important for material processing as welding, cutting and hardening. In the first part of this paper a CO2-laser system is described which produces max. 70000 laser pulses/sec with an average power of 1 kW. with this laser system welding experiments are performed on steel and aluminum surfaces. The aim of this paper is to clarify by experiments why the treatment of steel surfaces is different from the aluminum case.
