An arrangement is disclosed for geometrically shaping a radiation field, in particular the radiation field of a diode laser array (14) which propagates in the z direction and has a radiation cross-section which is larger in a direction defined as the x direction perpendicular to the z direction than in a direction defined as the y direction, which is perpendicular to the first, and has a lower radiation quality in said direction. X, y and z form a coordinate system. The radiation is grouped into radiation fractions in the x direction and the radiation fractions are reoriented as regards their radiation cross-sections. The arrangement has at least two reflective elements (22, 23) and is characterised in that each reflective element has a pair of reflection surfaces at approximately or exactly 90 DEG to each other. This opening angle is oriented against the direction of propagation. The line at which the reflection surfaces intersect is oriented at approximately below 45 DEG to the x direction. |
