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.

Abstract: The invention relates to an optical array for symmetrization of the beam of multiple sequentially fixed adjacent laser diodes, their respective output radiation being asymmetrical in relation to a first and a second direction that are perpendicular to each other. A cylindrical lens with sufficient isoplanacy is mounted on the tilted optical axis (z axis), which is perpendicular to the plane predetermined by the two directions (x, y). The lens collimates and displaces the output beam bundle of the individual laser diodes in the first direction (x). The cylindrical lens is mounted downstream a directional element that deflects the beam bundle of the individual laser diodes in the second direction (y) with different deflecting angles respectively in such a way that the centers of gravity of the individual beam bundles converge at a predetermined spacing.
