Abstract
A laser arrangement for use in a multi-beam laser sighting mechanism, which comprises a light source for producing at least one primary laser beam bundle and an optical beam divider with reflecting surfaces, by which at least one primary laser beam bundle can be split into at least two partial beam bundles, which extend perpendicularly to one another. The light source comprises two semiconductor lasers including light-emitting surfaces which have a longitudinal extent and a transverse extent, which are in a ratio of about 2.5:1 to about 4:1 to one another. The light-emitting surfaces of the semiconductor lasers are disposed so that the longitudinal extents of the light-emitting surfaces are rotated at an angle of 90° to one another and the primary beam bundles, which are produced by the two semiconductor lasers, can be superimposed before or at the beam divider.
