The development of LBW processes is driven by more complex laser-based welding processes made possible with the development of lasers of higher available power. Nevertheless, most laser-heads are based on refractive optics, limiting the capability to fully use this power. Multi-Plane Light Conversion (MPLC) is a fully reflective technology enabling complex beam shaping through a succession of phase plates. A MPLC-based laser head has been developed providing an annular shape. It presents a less than a 1mm focus shift. LBW as well as HLAW of steal up to 16kW is demonstrated with improved butt-joint configuration gap welds.
