Abstract
Disclosed herein are various embodiments for laser apparatuses. In an example embodiment, the laser apparatus comprises (1) a laser-emitting epitaxial structure having a front and a back, wherein the laser-emitting epitaxial structure is back-emitting and comprises a plurality of laser regions within a single mesa structure, each laser region having an aperture through which laser beams are controllably emitted, (2) a micro-lens array located on the back of the laser-emitting epitaxial structure, wherein each micro-lens of the micro-lens array is aligned with a laser region of the laser-emitting epitaxial structure, and (3) a non-coherent beam combiner positioned to non-coherently combine a plurality of laser beams emitted from the apertures.
