Abstract

Changes in the laser beam quality caused by pollution, wasting or defects of the optical components and the laser beam source usually only can be detected by time-consumptive methods. Therefore a system is developed to automate and simplify the diagnosis of the laser beam radiation. As a solution a laser beam analyzer is permanently integrated into the laser system, an ergonomic user software is developed and the analyzer, the tooling-machine, and the laser are controlled by one computer. The user of a laser machine is enabled with this system to detect changes in the beam quality in an early state by daily measurements which are easy and fast to be carried out. Failures can be retraced to defects of the laser source, the beam guiding system, and the focussing optics by the use of image processing methods and fuzzy algorithms. Furthermore it is possible to detect stealing changes in the beam mode structure. Within the scope of quality assurance the data can be archived according to EN ISO 900x to be able to assign processing parameters to work-pieces.
