| 英文摘要 | The present invention relates to a laser module comprising several sub-modules (1) arranged side by side along a first axis (10) on a common carrier. Each of said sub-modules (1) comprises a laser area (8) formed of one or several arrays of semiconductor lasers arranged on a surface of the sub-module (1). Laser radiation emitted by each of said semiconductor lasers (2) forms an intensity distribution in a working plane facing said surface of the sub-modules (1). The sub-modules (1) and laser areas (8) are designed and arranged such that the laser areas (8) of adjacent sub-modules (1) partly overlap in a direction perpendicular to said first axis (10). 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 (2) may be VCSEL with a rectangularly shaped emission. |
