Abstract
An arrangement is disclosed for geometrically shaping a radiation field, in particular the radiation field of a diode laser array which propagates in the z direction and has a radiation cross section which is larger, 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 Cartesian 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 (,) and is characterized in that each reflective element has a pair of reflection surfaces (,) at approximately or exactly 90° 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° to the x direction.
