The present invention relates to a laser module comprising several sub-modules () arranged side by side along a first axis () on a common carrier. Each of said sub-modules () comprises a laser area () formed of one or several arrays of semiconductor lasers arranged on a surface of the sub-module (). Laser radiation emitted by each of said semiconductor lasers () forms an intensity distribution in a working plane facing said surface of the sub-modules (). The sub-modules () and laser areas () are designed and arranged such that the laser areas () of adjacent sub-modules () partly overlap in a direction perpendicular to said first axis (). With such a laser module a thin laser line focus can be generated having a homogeneous intensity distribution along the length of the laser line independent on the distance between the module and the working plane. The individual semiconductor lasers () may be VCSEL with a rectangularly shaped emission.
