Abstract
The present disclosure relates to an optical irradiation unit for a plant for producing workpieces by irradiating powder layers of a raw material powder with laser radiation, comprising optical components for guiding and focussing a beam path of a first laser beam, and an optical splitting and coupling unit for splitting the first laser beam into at least two laser sub-beams and/or for coupling a second laser beam with a wavelength differing from the wavelength of the first laser beam into the beam path of the first laser beam. The disclosure also relates to a plant for producing workpieces by irradiating powder layers of a raw material powder with laser radiation, and to an associated method.
