TLDR
In this article, an optical arrangement is provided for balancing the beam of one or more high-power diode lasers (HP-DL) arranged one above another, where the beam which is known to diverge very differently in the direction of the pn junction and perpendicular to the emitters of an HP-DL arranged in a row is imaged at a point with high power density and high beam quality.Abstract:
An optical arrangement is provided for balancing the beam of one or more high-power diode lasers (HP-DL) arranged one above another. The beam, which is known to diverge very differently in the direction of the pn junction and perpendicular to the pn junction of the emitters of an HP-DL arranged in a row is imaged at a point with high power density and high beam quality the arrangement. Present for this purpose are optical devices which spread out the radiation in a mutually offset fashion in the direction of the pn junction while the radiation is superimposed perpendicular to the pn junction.read more

High power and high brightness diode-laser array for material processing applications
TL;DR: In this paper, the alignment arrangements for combination and fast-axis alignment of fast-axes of diode-laser beams are disclosed, which include providing each diodelaser with a corresponding alignable fastaxis collimating lens, providing individually alignable mirrors for steering an re-orienting beam from each device, and providing single diode laser slab-modules in which the diode laser beams can be pre-aligned to a common propagation-axis direction, and in which edges and surfaces of the slabs can be used to align the fast and slow-

Optical arrangement for symmetrizing the radiation of two-dimensional arrays of laser diodes
TL;DR: In this paper, the authors propose an optical arrangement for symmetrizing the radiation of a plurality of laser diodes that are arranged adjacently to each other and on top of each other, in a fixed manner relative to each another.

Optical arrangement for the use during a laser diode arrangement as well as laser diode arrangement with such an optical arrangement
TL;DR: In this paper, the degradation of beam quality at the focus, especially the widening of the focus caused by the nonconformities between the diode laser bars, or between the row of emitter elements, and the correction optics, can be effectively prevented.
