Abstract

Laser material processing is a technolgy with well controllable parameters. However, in order to control the parameters it is necessary to measure them. The basic parameters to be measured are usually the input power, the discharge current, the output power. But for a reliable operation the laser beam intensity distribution in the unfocussed part should be observed and the intensity in the focal area should be optimized. Additionally, the interaction between the laser and the material is depending on some material properties. So, the interaction can change, although all laser beam parameters are stable. In order to avoid this, a monitoring of the interaction is necessary. Examples for the before mentioned controls and diagnostics are given in the report.
