  • SINGLE-EMITTER LINE BEAM SYSTEM
    Publication number: 20170299875
    Abstract: A line beam system includes a single-emitter light engine including a plurality of separately spaced single-emitter diode lasers, each emitter configured to emit a diode laser beam. Beam spacing optics are optically coupled to the single-emitter light engine and situated to provide propagation axes of the diode laser beams in a close-packed parallel configuration. A light pipe having a longitudinal axis is situated to provide an output beam with a homogenized intensity profile across one or more axes by receiving a close-packed, combined beam and reflecting the beam within the light pipe. Coherence reduction is produced by diffraction of a close-packed combined beam or by propagation in the light pipe.
    Type: Application
