Abstract: A diode laser arrangement having a number of laser bars, wherein each laser bar has a number of emitters generating laser beams arranged offset in a stacked manner to one another, in at least two stacks to form the arrangement.

Abstract: Laser optical system for shaping at least one laser beam bundle made up of a plurality of laser beams generated respectively by an emitter, the emitters being offset relative to one another in a slow axis of the laser beams and at a distance from one another, with at least one plate fan located in the beam path of the laser beam bundle, which (plate fan) consists of several plates made of a light transmitting material, which (plates) are arranged offset in the direction perpendicular to their surface sides and are arranged with their surface sides in planes which enclose the beam direction and the fast axis of the laser beams, the plates forming respectively one first preferably flat plate narrow side for one beam entry and opposite this side one second preferably flat plate narrow side for the beam exit.

Abstract: The invention relates to a diode laser array with at least one laser bar and having at least one emitter and a heat sink array for cooling the at least one laser bar.

Abstract: By dividing at least the part of the correction optics of at least one row of emitter elements, i.e. the part acting as the fast axis collimator, into several segments, the degradation of beam quality at the focus, especially the widening of the focus, which is caused by the nonconformities between the diode laser bars, or between the row of emitter elements, and the correction optics, can be effectively prevented.

Abstract: The invention relates to a novel optical arrangement for use in a laser diode arrangement and a laser diode arrangement with one such optical arrangement. The arrangement uses a fast axis collimator that is segmented to maintain parallel beams and limit distortion.

Abstract: The invention relates to novel laser optics for shaping at least one laser eam which has a linear or strip-shaped cross section which extends in the first axial direction (X-axis) perpendicular to the beam axis (Z-axis), with at least two optical shaping elements which are located in succession in the beam path, and of which at least one is an element through which a laser beam has passed, and which form an optical arrangement, in which at least one laser beam is fanned out in one plane (Y-Z plane) perpendicular to the first axis (X-axis) into several parallel component beams which are offset against one another both in the first axial direction (X-axis) and also in the second axial direction (Y-axis) which is perpendicular to the beam axis (Z-axis) and perpendicular to the first axis (X-axis), and in which then the fanned-out component beams are combined.
