Abstract: In various embodiments, multiple laser emitters are arranged in one or more linear stacks and emit beams to one or more linear stacks of interleaving mirrors. The interleaving mirrors direct the beams to a shared exit point, thereby forming an output beam stack. The optical distances traversed by each beam from its emitter to the shared exit point are all equal to each other.

Abstract: In various embodiments, a laser head receives a laser output beam from a laser system or resonator without the use of a delivery optical fiber, and any asymmetry of the laser output beam may be maintained. The laser head may be physically rotatable to control orientation of the laser beam along a processing path on a workpiece.

Abstract: In various embodiments, a workpiece is processed utilizing one or more output beams emitted from a step-core optical fiber and formed from one or more input beams that may have non-circular beam shapes. In various embodiments, an input beam may be a variable-power laser beam having a laser-beam numerical aperture (NA) that varies as a function of the power of the laser beam. The step-core optical fiber may have an outer core NA that is greater than or equal to the laser-beam NA at a laser power of approximately 100%, an inner core NA that is less than or equal to the outer core NA, and an inner core NA that is greater than or equal to the laser-beam NA at a power of 50%.
