Embodiment Construction
[0052] next to refer to figure 1 and image 3 A first exemplary embodiment of a method for recovering unused electromagnetic radiation energy of an optical processing device 1 for processing a workpiece 5 and a typical configuration of an optical processing device 1 with a recovery device 6 are further explained, which currently It is a laser processing device. The optical processing device 1 comprises a laser light source 2 , which is preferably a diode laser with a plurality of individual emitters which are capable of emitting electromagnetic radiation (laser light) 4 during operation. Alternatively, CO can also be used 2 - A laser as laser light source 2 . Instead of laser light sources, for example, (high-power) light-emitting diodes can also be used, the optical power of which has increased rapidly over the past few years through technical further developments and which therefore have a foreseeable use in optical processing devices 1 potential as a light source.

Description
technical field [0001] The invention relates to a method for recovering unused optical radiation energy of an optical processing device, a recovery device and an optical processing device. Background technique [0002] Over the past few years, the technological importance of optical processing devices, in particular laser processing devices, by means of which different types of materials can be processed by applying electromagnetic radiation, in particular laser light, has increased considerably. To date, laser light sources with an optical radiation power of significantly more than 10 kW have been rarely used in industrial laser processing installations. New types of processing methods also require laser light sources with significantly higher power. Mention may be made in this context, for example, of laser processing devices for thermal processing of metals, for adapting material properties in functional layers or as a supplement to conventional furnaces in the productio...
