Abstract：
 This invention is the passive heat dissipating small sink semiconductor laser strip. It relates to the structure and packaging technology of the passive heat dissipating small sink semiconductor laser strip. The said heat sink is 10-12mm wide. The front end is staircase structure. The first step is 0.3-1mm high and 1-2mm long. The whole heat sink is 3-6mm high and 19-25mm long. The said illuminating medium is arranged at the front edge of the first step. This invention further decreases thermal resistance between illuminating medium and heat dissipating face of heat sink.
