    FIGURE 1. An AFX laser incorporates all-fiber beam shaping, which allows rapid switching of the output beam size and shape. The beam profile can be tuned between true single-mode and a ring, plus a variety of shapes in between. When interacting with the workpiece, ring- and saddle-shaped beams create significantly less soot and spatter.
