BRIGHT DIODE-LASER LIGHT-SOURCE

摘要

A light-source includes a plurality of diode-laser bars. The diode-laser bars are arranged in a parallel array. The diode-laser bars are mounted on a planar surface of a common heat-sink and are spaced-apart from each other in the emission-direction. Each diode-laser bar has one optical waveguide associated therewith. The waveguides collect light emitted from the diode-laser bars and deliver the collected laser-light to an output. In one arrangement the diode-laser bars are mounted such that the emission-direction is parallel to the planar surface of the heat-sink. In another arrangement the diode-laser bars are mounted on the planar surface via wedge submounts such that the emission-direction is at an acute angle to the planar surface and the spacing of the diode-laser bars is selected such that the optical-waveguides can be straight yet still extend over adjacent diode-laser bars.
