Abstract

A multibeam laser light source, comprising a plurality of individual laser light sources arranged in an array and including a first and a second laser light source for emitting respective light beams spaced from one another, said first laser light source having a resonator with a given pump energy distribution therethrough, the spacing of the light beam emitted by said first laser light source from the light beam emitted by said second laser light source being variable by varying said given pump energy distribution through said resonator of said first laser light source; an image-setting or imaging device therewith; a printing form exposer with the imaging device combination; a printing unit with the imaging device combination; and a printing press with the printing unit combination.
