Abstract

The invention relates to a laser-processing unit, in particular a laser-welding unit, having a laser beam source (2) for generating a laser beam (LS) and having a pivotable focusing unit (8) 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 (4) is arranged in the beam path of the laser beam (LS) between the laser beam source (2) and the focusing unit (8), which mirror is assigned an observation device (20) in such a manner that the optical axis (22) of this device coincides with the axis (24) 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).
