Abstract:
1. A laser module comprising several sub-modules arranged along a first axis side by side on a common carrier, each of said sub-modules comprising a laser area formed of one or several arrays of semiconductor lasers on a surface of the sub-modules ( 1 ) and laser radiation emitted by said semiconductor lasers forming an intensity distribution in a working plane facing said surface of the sub-modules, wherein said sub-modules and laser areas are designed and arranged such that projections of the laser areas of adjacent sub-modules partly overlap in a direction perpendicular to said first axis, wherein said laser areas are formed of an arrangement of said arrays of semiconductor lasers, which comprises two parallel side edges, said parallel side edges of adjacent laser areas being parallel to one another and tilted by an angle β to said first axis, wherein 0°<β<90°, wherein said laser areas are arranged to generate a homogeneous intensity distribution in the working plan in a direction parallel to the first axis by means of the tilted arrangement of the laser areas.
