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.

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.

Abstract: In various embodiments, laser devices feature means, such as fasteners, for attaching a laser package to a cooling plate, which allow motion of the laser package in response to thermal cycles resulting from operation of a beam emitter therewithin. Embodiments of the invention additionally or instead include laser devices featuring segmented barrier layers for electrically isolating the laser package from the cooling plate.
