The diagnostic of the distribution of the radiation of CO sub 2 high power lasers has proved to be an efficient measurement device for the development of beam sources and their application. They help to achieve an exact adjustment of lasers or detect changes within the laser beam which could be the reason for faulty processing. As a central element of control systems, industrial application in production may only be effected if the considerable number of informations which result from the measurements is reduced to a few characteristic parameters. By means of these, criteria for control may be determined. This enables and facilitates a description of the correlation laser beam:processing device or process. Suggestions for the definition and coordination.
