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, one or more optical elements are utilized to alter the numerical aperture of a radiation beam received from an optical fiber in order to accommodate the properties of a downstream collimator within a laser delivery head.

Lens arrangements for varying numerical aperture in laser delivery 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, optical fibers have arrangements of core, annular core, and cladding regions enabling variation of beam shape and/or beam parameter product and may be utilized for the processing (e.g., welding, cutting, drilling, etc.) of various workpieces.

Optical fiber structures and methods for beam shaping

In various embodiments, the beam parameter product and/or beam shape of a laser beam is adjusted by directing the laser beam across a path along the input end of a cellular-core optical fiber. The beam emitted at the output end of the cellular-core optical fiber may be utilized to process a workpiece.

Laser systems utilizing cellular-core optical fibers for beam shaping

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, 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.

Material processing utilizing a laser having a variable beam shape

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.
