LASERANORDNUNG, VORZUGSWEISE LASERBEARBEITUNGSMASCHINE

摘要

The apparatus has at least one optical element (6, 8) which is located in the path of the laser beam (5) and is at least partially translucent to the beam. There is at least one unit (10, 11) for determining the temperature of at least one optical element (6, 8) from the intensity of light radiated from the element. The laser beam is control-led on the basis of this light intensity in such a way that the temperature of the particular optical element is appropriately influenced.
