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.

Assembly techniques and cooling manifold configuration for high-power laser systems

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.

Laser system with staircased slow-axis collimators

In various embodiments, a laser emitter such as a diode bar is cooled during operation via jets of cooling fluid formed by ports in a cooler on which the laser emitter is positioned. The jets strike an impingement surface of the cooler that is thermally coupled to the laser emitter but prevents direct contact between the cooling fluid and the laser emitter itself.

Packages for high-power laser devices

In various embodiments, a spring is utilized to fix an optic to a mechanical mount in a laser system. Such springs may consist of a single length of elastic material having first and second ends. The length of elastic material may define first and second off-center bends providing first and second base portions, as well as a central bend that is generally U-shaped and that defines first and second contact portions. The first and second contact portions are opposed to each other across the central bend to thereby resist compression of the first and second contact portions toward the first and second base portions.

Methods and devices for fixing optics to mechanical mounts in high-power laser systems

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.

Systems and methods for addressing pumping of thermal interface materials in high-power laser systems

In various embodiments, laser beams of two different wavelengths are utilized, sequentially and/or simultaneously, to process workpieces in various processing stages such as melting, piercing, cutting, and welding.

Dual-wavelength laser systems and material processing utilizing such systems

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.

Condensation prevention for high-power laser systems

In various embodiments, the concentration and deposition of siloxane materials within components of laser systems, such as laser resonators, is reduced or minimized utilizing mitigation systems that may also supply gas having low siloxane levels into multiple different components in series or in parallel.

Siloxane mitigation for laser systems

In various embodiments, laser emissions are steered into different regions of an optical fiber, and/or into different optical fibers, in a temporal pattern such that an output has different spatial output profiles. The temporal pattern has a frequency sufficient such that a workpiece is processed by an effective output shape combining the different spatial output profiles.

Material processing utilizing high-frequency beam shaping

In various embodiments, a beam-parameter adjustment system and focusing system alters a spatial power distribution of a radiation beams before the beam is coupled into an optical fiber or delivered to a workpiece.
