Abstract
Laser processing devices consist of process optics (25) for converting the laser beam, these optics being connected by means of a connection element (protection tube 24) to a laser source, for example a CO.sub.2 laser 20. Depending on the process to be carried out, an appropriate process adaptor (28) has to be associated with the process optics (25). In order to be able to use a laser processing device as economically as possible, efforts are made to use the laser processing device both for cutting and welding and also for surface treatment, using as little conversion work as possible. In order to simplify this conversion process, the invention proposes providing the process optics (25) with universal connections (53; 66), by means of which the process adaptors (28) and/or mirrors (deflection mirror 44; focusing mirror 45) can be fastened to the casing (29) of the process optics (25) without any noticeable fitting and positioning requirements. By this means, the same casing (29) can be used for all the conceivable types of processing.
