Abstract
The invention relates to a laser-processing unit, in particular a laser-welding unit, having a laser beam source ( ) for generating a laser beam (LS) and having a pivotable focusing unit ( ) for pivoting the laser beam (LS) about two axes of rotation (x, y) and for focusing the laser beam (LS) in a focus (F). A dichroic mirror ( ) is arranged in the beam path of the laser beam (LS) between the laser beam source ( ) and the focusing unit ( ), which mirror is assigned an observation device ( ) in such a manner that the optical axis ( ) of this device coincides with the axis ( ) of the laser beam (LS) as it propagates downstream of the dichroic mirror, as seen in the direction of propagation of the laser beam (LS).
