DEVICE AND METHOD FOR BEAM FORMING

摘要

The invention relates to a device for beam forming, comprising at least two laser light sources (1a, 1b, 1c) capable of emitting laser radiation (2a, 2b, 2c), and optical means capable of influencing the laser radiation (2a, 2b, 2c) such that the laser radiation (2a, 2b, 2c) has an intensity distribution (8) in a working plane (7) at least partially corresponding to a top-hat distribution at least with regard to one direction, wherein the laser beam (2a, 2b, 2c) may be at least partially overlapped by said optical means, and wherein the laser beam (2a, 2b, 2c) is a single-mode laser beam at least with regard to a direction (X) perpendicular to the distribution direction (Z).
