Abstract
Official abstract text for this publication.
The present invention relates to a laser device comprising an array of several large area VCSELs ( 101 ) and one or several optics ( 201, 202 ) designed and arranged to image the active layers of the VCSELs ( 101 ) of said array to a working plane ( 501 ) such that the laser radiation emitted by the active layers of all VCSELs ( 101 ) or of subgroups of VCSELs ( 101 ) of the array superimposes in the working plane ( 501 ). The proposed laser device allows the generation of a desired intensity distribution in the working plane without the need of an optics specially designed for this intensity distribution or beam profile.
First claim
Opening claim text (preview).
The invention claimed is: 1. A laser device comprising: an array of several large area vertical cavity surface emission lasers, each of said lasers comprising an active layer emitting laser radiation; at least one optics configured and arranged to image the active layers of the lasers of said array to a working plane such that the laser radiation emitted by the active layers of all lasers or of subgroups of lasers of the array superimposes in the working plane; and, wherein sa…
