1. A display system comprising:
an optical engine comprising:
a first set of laser light sources; and
a second set of laser light sources;
a beam combiner configured to combine a plurality of laser light beams output by the first set of laser light sources and the second set of laser light sources and to output a first elliptical laser light beam corresponding to the first set of laser light sources and a second elliptical laser light beam corresponding to the second set of laser light sources, wherein the first elliptical laser light beam propagates along a first optical path and the second elliptical laser light beam propagates along a second optical path that is different from the first optical path; and
a scan mirror, wherein the first elliptical laser light beam and the second elliptical laser light beam are both directed onto the scan mirror.
