The invention relates to a light and high-thermal-conductivity laser crystal heat sink and a manufacturing method. The light and high-thermal-conductivity laser crystal heat sink comprises a heat sinkbody, an array mounting surface, a positioning side surface, a laser crystal welding bottom surface, array mounting threaded holes and heat sink mounting unthreaded holes, the heat sink body is madeof an aluminum-based composite material, the outer surface of the heat sink body is plated with a gold-plated layer, and the gold-plated layer is used for improving the corrosion resistance of the heat sink body and improving the weldability of the laser crystal. Compared with a traditional tungsten-copper heat sink, the light and high-thermal-conductivity laser crystal heat sink provided by the invention has the advantages that the weight can be reduced by 80% or above while the heat dissipation requirement is met, the weight can be reduced to a great extent, the high-integration and light-weight development requireme
