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, 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, pointing errors in a non-wavelength-beam-combining dimension of a laser system are at least partially alleviated via staircased collimation lenses.

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.

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, laser resonator modules produce output beams via manipulation of input beams on opposite sides of the module. The input beams are emitted by one or more beam emitters that may be cooled using a liquid coolant cavity. The liquid coolant cavity may be isolated from optical elements utilized to manipulate the input beams, at least in part, by an isolation wall protruding from the base plate of the resonator module.
