A method for joining an optical crystal to a substrate includes radiating a pulsed laser beam through the optical crystal or through the substrate onto a surface of an intermediate layer between the optical crystal and the substrate, and forming a fusion zone in the intermediate layer between the optical crystal and the substrate by the radiation of the pulsed laser beam, thereby integrally joining the optical crystal and the substrate.

A laser head apparatus that enables switching between a laser beam and a purging stream. The laser head apparatus includes a bracket that provides for translation and rotation of the laser optics and purging nozzle. The laser optics and purging nozzle are located on opposite sides of the bracket and may be rotated to different rotational positions around a center axis of the bracket and translated to different linear positions along a length of the bracket. Methods of removing material using the laser head apparatus to between a laser beam and a purging stream are also provided.

A processing apparatus includes: a beam irradiation apparatus that is configured to irradiate an object with an energy beam; and a beam deflection apparatus that is configured to change a propagating direction of the energy beam toward the beam irradiation apparatus, wherein when the energy beam propagating toward the beam irradiation apparatus from the beam deflection apparatus propagates in a first direction, the beam irradiation apparatus emits the energy beam in a second direction, and when the energy beam propagating toward the beam irradiation apparatus from the beam deflection apparatus propagates in a third direction that is different from the first direction, the beam irradiation apparatus emits the energy beam in a fourth direction that is different from the second direction.

An apparatus for laser processing of very wide non-woven fabric materials at high speeds. This invention enables a laser beam to sever, perforate and pattern a large piece of fabric materials planarly disposed at regular or irregular spatial intervals over the entire width while the fabric passes from one roller to another roller at high speeds by precisely managing focus and intensity of the beam at the focal point on the web. A control system managing the laser processing system enables rapid reconfiguration of perforation patterns. The fabric can be woven or nonwoven, homogeneous or nonhomogeneous material with uniform or nonuniform thickness. An optical sensor is provided to sense the laser processing as it is performed and provide feedback to a system controller to optimize laser processing performance in real time.

The invention relates to a method for producing an axle housing of a vehicle axle, by means of integrally connecting an axle tube (1) to an axle shaft (2) which is positioned on the longitudinal axis (L) of the axle tube, is equipped with bearing surfaces (3) for mounting a vehicle wheel, and has a tube cross-section facing said axle tube (1) which is substantially the same as the tube cross-section of the axle tube. In order to develop a welding method for the production of an axle housing that consists of an axle tube and an axle shaft secured thereto, which method is optimised in terms of the dynamic loads to which the axle housing is typically subjected in a driving operation, the method comprises the following steps: •—arranging the axle tube (1) and the axle shaft (2), with the abutting surfaces of their tube cross-sections positioned coaxially to one another, in a workpiece receiving portion of a welding installation (10), said welding installation additionally comprising an arc welding device (11) and a laser welding device (12) which is operated in parallel, •—continuously miming a weld seam (20) in the peripheral direction of the tube cross-sections, both welding devices (11, 12) being directed, actively and from the outside, onto substantially the same peripheral section of the abutting surfaces, wherein the laser beam (S) meets the outside (14) of the tube at right angles, and intersects the longitudinal axis (L) of the axle tube (1), and •—stopping running the weld seam (20) once this has passed over a peripheral angle of at least 360°. A corresponding axle housing is also disclosed.

A visible light laser system and operation for welding materials together. A blue laser system and operation for welding conductive elements, and in particular thin conductive elements, together for use in energy storage devices, such as battery packs.

A debris remover includes an air nozzle that blows air from one side toward a processing point at which a workpiece is irradiated with a laser beam, a suction duct having a suction opening for sucking debris that has scattered to another side due to the air blown from the air nozzle, vortex generators formed on the processing point side of the suction opening for guiding the scattering debris into the suction duct, and a C-shaped sealing plate that is formed in such a manner as to surround the vortex generators from a rear side and reduces a space defined between the suction opening and the workpiece.

A method of separating a substrate includes directing a laser beam into the substrate such that a focal line is formed with at least a portion of the laser beam focal line within a bulk of the substrate at an oblique angle with respect to a laser-incident surface of the substrate. The laser beam focal line is formed by a pulsed laser beam that is disposed along a beam propagation direction. The method further includes pulsing the pulsed laser beam from a first edge of the substrate to a second edge of the substrate in a single pass. The laser beam focal line generates an induced multi-photon absorption within the substrate that produces a damage track within the bulk of the substrate along the laser beam focal line, and the damage track is at an oblique angle relative to the laser-incident surface of the substrate.

A method and device for laser cladding by independently heating the cladding material and the surface of the workpiece consist in formation of the series of parallel annular laser beams, possibly different wavelengths, with an adjustable distribution of laser radiation power across the annular beams. The annular beams are transformed into a series of conical beams which are separately focused along a single optical axis, along which the cladding material is fed. The device can be supplemented with a cylindrical mirror for the multipass laser radiation through the stream of cladding material with the possibility of the laser radiation return to the laser resonator.
