An optical arrangement converts a laser beam into a line-type beam having a line-type beam cross-section that extends along a line direction with a non-vanishing intensity. The arrangement has: reshaping optics having: an input aperture through which the laser beam is radiated in; and an elongate output aperture, the reshaping optics being configured such that the laser beam radiated in is converted into a beam packet with beam segments that emerge through the output aperture; homogenization optics, which contribute to the conversion of the beam packet into the line-type output beam, and by which different beam segments are mixed and superposed along the line direction; and redirection optics configured to redirect the laser beam such that an incidence position/direction of laser beam on the input aperture is changed in dependence on time.

Optical arrangement and laser system

A system for monitoring the temperature of a component includes a temperature sensor that is in thermal contact with the component. The temperature sensor includes a thermocouple and connecting lines. The thermocouple is mounted in an electrically conducting fashion onto a flexible printed circuit board tape in which the connecting lines are integrated. The component is a mirror and the flexible printed circuit board tape is disposed as an electrical insulator between the thermocouple and the mirror.

Temperature monitoring system

In a laser processing machine for processing workpieces using a laser beam (), a telescope () for widening the laser beam () comprises an ellipsoidal mirror () and a paraboloidal mirror () whose axes of rotation () extend parallel, in particular collinear, to each other. This orientation permits precise production of the reflecting surfaces of the two mirrors through one single clamping (e.g. through diamond lathe) such that later adjustment is not required.

Laser processing machine

A device for beam guiding a laser beam with at least one optical element, which is positioned with a retaining element to a supporting section, and with a clamping element, which fixes the optical element to the supporting section of a housing section, wherein the housing section having the supporting section has a fastening section on which the clamping element engages for the central introduction of a retaining force and positions the optical element to the supporting section with the interposition of at least one retaining element.

Device for beam guiding a laser beam

A laser has at least two coaxial electrode tubes spaced apart to provide a laser cavity therebetween and a cooling system including cooling coils about the outer surface of the outer electrode and about the inner surface of the inner electrode and in heat exchange contact therewith. Support pipes are provided about the outside of the outside cooling coil and about the inside surface of the inner cooling coil. The cooling coils are deformed into improved heat exchange contact with the electrode tubes by internal pressure and may be softened by annealing or the like before the application of the deformation pressure.

Gas laser with cooled coaxial electrode tubes

A gas laser gas has an elongated cavity in which are disposed a first elongated electrode tube having an inner diameter, and a second elongated electrode tube disposed coaxially within the first electrode tube and having an outer diameter smaller than the inner diameter of the first electrode tube and spaced therefrom so as to provide a gas discharge chamber therebetween. The second electrode tube provides a gas exit chamber therewithin, and the first electrode tube is spaced from the wall of the cavity to provide a gas entry chamber thereabout. The electrode tubes permit gas to flow therethrough from the gas entry chamber to the gas exit chamber. The electrodes may be formed from a gas permeable material such as sintered metal, or formed from a non-permeable material with openings therein. The electrodes may have coolant flowing therethrough.
