OPTICAL IRRADIATION UNIT FOR A PLANT FOR PRODUCING WORKPIECES BY IRRADIATION OF POWDER LAYERS WITH LASER RADIATION |
摘要 |
The present invention relates to an optical irradiation unit (10) for a plant (100) for producing workpieces by irradiating powder layers of a raw material powder with laser radiation, comprising optical components (40, 50, 60, 70) for guiding and focussing a beam path of a first laser beam (200), and an optical splitting and coupling unit (62, 64, 66) for splitting the first laser beam (200) into at least two laser sub-beams and/or for coupling a second laser beam (300) with a wavelength differing from the wavelength of the first laser beam (200) into the beam path of the first laser beam (200). The invention also relates to a plant (100) for producing workpieces by irradiating powder layers of a raw material powder with laser radiation, and to an associated method. |
