<p>A method in connection with laser use, wherein one or more laser beams (R) emitted by one or more laser sources (Y) are focused by means of beam guiding elements (1) on a fusing spot (S) , whereat a filler (L) delivered thereto is melted, especially for performing a welding, coating, piece manufacturing and/or the like process, the employed filler comprising a substantially solid-state, elongated filler material (L; L1) , such as a wire or the like, which is fed by means of a delivery system (X) to the fusing spot (S) centrally relative to said one or more laser beams (R) focusing on the fusing spot (S) . The one or more laser beams (R) are diverged (I) with a multi-segment mirror (1a) , especially for maintaining the symmetry of the intensity distribution thereof, whereby beams or divisional beams (R' ) , reflecting from its various segment elements (1a') in substantially divergent directions, are converged (II) on the fusing spot (S) by means of a condenser system (1b) included in the beam guiding elements (1) .</p> |
