Abstract

The beam parameters of a laser system for material processing are supposed to remain constant at the workpiece surface under all operating conditions. In particular this means: a constant focus diameter and focal depth, constant focus position and constant laser energy and laser power. For economic reasons the efficiency and the beam quality should be high, which guarantees a wide field of applications. Asymmetry in the processing direction must be avoided, the beam cross section, except in special cases, should be circular and the beam polarization circular or random.
