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, laser resonators include enclosed cooling manifolds defining protrusions each configured to conduct heat-exchange fluid to a beam emitter in the resonator. Installation of such cooling manifolds may be facilitated via use of a rigid installation tool functioning as a mechanical reference, prior to installation of the beam emitters and sealing of the beam emitters to the cooling manifold.

Abstract: In various embodiments, laser systems or resonators incorporate two separate cooling loops that may be operated at different cooling temperatures. One cooling loop, which may be operated at a lower temperature, cools beam emitters. The other cooling loop, which may be operated at a higher temperature, cools other mechanical and/or optical components, for example optical elements such as lenses and/or reflectors.
