Abstract

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.
