In various embodiments, multiple laser emitters are arranged in one or more linear stacks and emit beams to one or more linear stacks of interleaving mirrors. The interleaving mirrors direct the beams to a shared exit point, thereby forming an output beam stack. The optical distances traversed by each beam from its emitter to the shared exit point are all equal to each other.

Single emitter stacking for wavelength-beam-combining laser systems

In various embodiments, alignment systems for laser resonators generate near-field and/or far-field images of input beams produced by the laser resonators to enable the alignment of the input beams.

Systems and methods for alignment of wavelength beam combining resonators

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, 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

A system and method for stabilizing and combining multiple emitted beams into a single system using both WBC and WDM techniques.

Two-dimensional multi-beam stabilizer and combining systems and methods

In various embodiments, optical repositioners and/or angled dispersive elements are utilized to manipulate portions of an input laser beam emitted by a group of laser emitters in order to form a multi-wavelength output beam having a high beam quality factor.

Wavelength beam combining laser systems with high beam quality factor

In various embodiments, laser delivery systems feature one or more optical elements for receiving a radiation beam and altering the spatial power distribution thereof, a lens manipulation system for changing a position of at least one optical element within the path of the radiation beam, and a controller for controlling the lens manipulation system to achieve a target altered spatial power distribution on a workpiece.

Optical element arrangements for varying beam parameter product in laser delivery 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 beam parameter product and/or beam shape of a laser beam is adjusted by coupling the laser beam into an optical fiber of a fiber bundle and directing the laser beam onto one or more in-coupling locations on the input end of the optical fiber. The beam emitted at the output end of the optical fiber may be utilized to process a workpiece.

Laser systems utilizing fiber bundles for power delivery and beam switching

In various embodiments, laser delivery systems feature variable polarizers and beam shapers for altering the polarization and/or shape of the output beam for processing of various materials. The polarization and/or shape of the beam may be varied based on one or more characteristics of the workpiece.

Polarization-adjusted and shape-adjusted beam operation for materials processing

In various embodiments, workpieces are processed, e.g., via welding or cutting, while the shape and/or one or more other parameters of the laser processing beam are altered. The shape and/or one or more other parameters of the laser processing beam may be varied based on one or more characteristics of the workpiece.
