Abstract
A process and device for forming and guiding the radiation field or one or several solid and/or semiconductor lasers, in particular the radiation field of an array or field arrangement of one or several solid and/or semiconductor lasers, comprise radiation transformation optics with refractive elements that generate a defined radiation field. The device is characterized in that the radiation field (4) is subdivided into at least two radiation fractions according to predetermined data. Each radiation fraction enters an associated refractive element (6, 15, 19, 21, 23, 24) with predetermined co-ordinates. Each refractive element (6, 15, 19, 21, 23, 24) refracts the corresponding radiation fraction on at least one of its surfaces (7) so that the radiation fractions leave the refractive elements (6, 15, 19, 21, 23, 24) with output co-ordinates and/or propagation directions modified in relation to each other.
