Abstract : A process for bonding two diamond surfaces together by (1) forming a layer of opaque non-diamond carbon material between the two diamond surfaces; (2) pressing the diamond surfaces together with the opaque non-diamond material sandwiched between the diamond surfaces; (3) used pulse lased light to quickly melt all the opaque non-diamond carbon material before a significant amount of heat is lost through the diamond surface; and then (4) allowing the resulting carbon melt to cool and solidify as polycrystalline diamond which grows homoepitaxially from the diamond surfaces, bonding those surfaces together.
