Abstract: In various embodiments, multiple laser emitters are helically arranged around a central axis and emit their individual beams toward the central axis. A collection of mirrors is disposed at the central axis, and each mirror is angled so that the reflected beams all exit the helical stack, in parallel and vertically stacked, in the same direction toward a shared exit point.

Abstract: In various embodiments, emitter modules include a laser source and (a) a refractive optic, (b) an output coupler, or (c) both a refractive optic and an output coupler. Either or both of these may be situated on mounts that facilitate two-axis rotation. The mount may be, for example, a conventional, rotatively adjustable “tip/tilt” mount or gimbal arrangement. In the case of the refractive optic, either the optic itself or the beam path may be adjusted; that is, the optic may be on a tip/tilt mount or the optic may be replaced with two or more mirrors each on tip/tilt mount.
