Laser beam through focus mirror,then after x and y galvanometer scanning focused on the material surface.If the coordinate origin is flat,then the spot is the smallest.
When galvanometer scanning laser beam away from the origin,then the laser beam hit the surface is not in focal plane.(the focal plane is spherical, but the surface is flat), where the focused spot becomes large, so that the entire workpiece plane hit the mark spot diameter is not the same, marking the line width is not the same. If add a dynamic focusing lens in front of the focusing lens, when the galvanometer scanning the laser beam away from the origin, by changing the dynamic focus position remains the focus still on the surface of the workpiece, the spot where the diameter and origin as large as the diameter of the spot. By moving dynamic focusing mirror, so that the spot diameter in the marking range all same and spot diameter smaller. So to achieve a small spot, large-scale, high-speed light-pumped solid-state laser marking machine.
