Abstract

A diode laser device includes a heat diffusing substrate made from a material that is a good conductor of heat, in one face of which is formed a system of parallel ribs and grooves, the ribs being identical and equidistant, and a plurality of semiconductor arrays incorporating the diodes and housed longitudinally in the grooves. The grooves have an at least approximately triangular cross-section joined to the substrate by one side and each semiconductor array is fixed flat to an oblique flank of one of the ribs.
