A laser system includes at least two sources configured to provide at least two spatially separated laser beams, and a mount configured to mount the at least two sources along an arc, the arc defining an angular coordinate and a radial coordinate, wherein an axial coordinate is orthogonal to the angular coordinate and the radial coordinate, and the spatially separated laser beams are separated in the axial coordinate. The mount is further configured to mount the at least two sources providing thereby an offset of the laser beams in the axial coordinate such that the laser beams interleave in the axial direction at a center region of the arc.
