A device for projecting a laser beam onto a workpiece includes at least one first optical element, at least one second optical element, and at least one third optical element. The at least one first optical element is configured to project the laser beam onto the at least one second, in particular diffractive, optical element. The at least one second optical element is configured to convert an intensity profile of the laser beam. The at least one third optical element is configured to project the laser beam onto the workpiece. The device is configured such that a diameter of the laser beam on the workpiece can be varied while maintaining the intensity profile with a stationary workpiece.

Device and method for laser material processing

A method is provided for processing a workpiece using laser radiation, particularly for the purpose of laser ablation. At least one laser beam is provided, which is affected using at least one changeable beam forming device. The laser beam subsequently impinges upon at least one processing area of the workpiece. Using the beam forming device, at least one specified adjustable beam profile is impressed upon the laser beam at the location of the processing area configured.

Method and device for processing a workpiece using laser radiation

The invention relates to a protective device () for the laser machining of holes () in at least one component () by means of a laser beam (), wherein the protective device () is positionable in the beam direction downstream of the beam-exit-side end () of a hole () to be machined in the component wall (), in order to protect an adjoining rear space having a component wall (), opposite the hole (), of the component () from the incident laser beam. The protective device () according to the invention is formed from a composite made of a matrix composed of polyether ether ketone plastics material and fibers embedded therein, wherein the fibers are embedded such that, with respect to their particular fiber extending direction, they extend in a criss-cross manner in the plastics material and are distributed at approximately the same density in the volume of the plastics material of the protective device (). The fibers are configured as glass fibers or carbon fibers in order to split the laser beam () passing into the composite and to reduce the energy density thereof.

Protective device for the laser machining of holes in components

An aerostatic bearing and a linear compressor that includes the aerostatic bearing. In an exemplary embodiment, the aerostatic bearing includes a guide element including holes, and a body structured to move along a surface of the guide element. The holes may include a first section close to the body, of which at least one part area features a cross-sectional surface substantially constant over its entire length which is smaller towards the body than another cross-sectional surface of an area away from the body. A method for producing a hole in an element, using a laser beam, for producing the aerostatic bearing is also disclosed.

Aerostatic bearing and method for production thereof

A device for introducing holes into a workpiece has a laser beam source for producing at least one laser beam which may be directed toward the workpiece. A nozzle system is provided having at least one nozzle which may have a gas under pressure applied to it, the gas flow exiting the nozzle being aligned in relation to the workpiece surface in such a way that molten particles detached from the workpiece are guided away from the hole produced by the laser beam.
