Device and method for beam shaping

摘要

A device for beam shaping includes a heat dissipation body having an upper side with a planar section and a plurality of laser elements next to one another on the planar section of the upper side that respectively emit a ray bundle having a fast-axis divergence and, perpendicular thereto, a slow-axis divergence. A reflection element is arranged such that the ray bundles of the individual laser elements extend parallel to one another and at an elevation angle of greater than 0° and less than 90° with respect to the planar section after exactly one reflection at the associated reflection element. The reflected ray bundles are stacked in the optical path downstream of the reflection elements in a first plane perpendicular to the beam direction and a connecting line, lying in the first plane, of the centers of the reflected ray bundles extends perpendicular to the direction of the slow axis.

1. A device for beam shaping, comprising:
a heat dissipation body including an upper side, the upper side including a planar section; and a plurality of laser elements arranged next to one another on the planar section of the upper side, each of which respectively emit a ray bundle which has a fast-axis divergence and a slow-axis divergence, the slow-axis divergence being perpendicular to the fast-axis divergence, wherein a reflection element is associated with each laser element, the reflection element being arranged such that the ray bundles of the individual laser elements extend parallel to one another and at an elevation angle of greater than 0° and less than 90° with respect to the planar section after exactly one reflection at the associated reflection element, wherein the reflected ray bundles of the individual laser elements are stacked in an optical path downstream of the reflection elements in a first plane perpendicular to the beam direction of the reflected ray bundles, and a connecting line, lying in the first plane, of a center of each of the reflected ray bundles extends perpendicular to the direction of the slow axis, wherein the slow axis direction of the ray bundle emitted by the laser elements is in a common plane, and wherein the ray bundles emitted by the laser elements extend parallel to one another in an emission plane, which lies parallel to the planar section.
