Laser light source and an optical system for the shaping of light from a layer sequence of stripe lasers

摘要

An optical shaping system for a strip of laser layer product for the formation of a laser beam from a strip of laser layer product, in which a plurality of stripe lasers, each of which is arranged a plurality of one-dimensional half conductor laser elements, along a direction are layered, the both to the direction of arrangement of the half conductor laser elements as well as to the direction of travel of the laser beam runs vertically, comprising:a refractive optical system, in which, a second laser beam group consisting of relatively with respect to a first laser beam group is displaced along the the direction of the layer, wherein the first laser beam group consisting of the laser beam group on the one side of the laser beam groups of the strip laser layer product with a line segment along the the direction of the layer is output as a boundary line, and the second laser beam group consisting of the laser beam group on the other side, andan optical transmittance - / a reflexion system to the orientation of said shifted first and second laser beam groups along the the direction of the layer,wherein the optical transmittance - / a reflexion system a first reflection element, said one of said first and second laser beam reflected groups in one plane, which contains the direction of alignment and the direction of travel, and a second reflection element, in which the laser beam group consisting of entry, which was reflected by the first reflecting element, wherein the second reflection element a reflection area for reflecting of one of the first and second groups and a transmission range for transmitting the other group comprises alternately into strips are formed along the the direction of the layer.
