Multibeam laser source unit for image setting device, sets spacing of beam emitted by primary source different from that of beam from secondary source, by varying pump energy distribution of resonator of primary source

摘要

A controller sets spacing of light beam emitted by primary laser source (12) different from that of light beam emitted by secondary laser source, by varying pump energy distribution of resonator of primary laser source. Independent claims are also included for the following: (1) image setting or imaging device; (2) printing form exposer; (3) printing unit; (4) printing press.
