英文摘要	1487010 Lasers STANDARD TELEPHONES & CABLES L td 1 April 1975 13203/75 Heading H1C A semiconductor laser chip 14, Fig. 2; is attached to a heat sink 12 forming part of a laser stud mount comprising the heat sink, a base 10 and a threaded stem 11, one circuit connection to the chip being provided by the stud mount, while the other connection is effected by a metallic strip 16 attached to and insulated from the base 10 and bearing against the chip. A secondary output path for laser radiation, e.g. for monitoring, is provided by a clad light guide 13 extending through the stud. Insulation of the metallic strip from the stud mount is provided either by two annuli of insulating material or by embedding the strip in a single ceramic ring, attachment to the base being effected by epoxy resin or by metallizing and soldering. In a modification, Fig. 8, the metallic strip 80 is cranked as shown so as to be uniformly spaced from the base and heat sink. In a further modification, Fig. 9, the metallic strip 90 is bifurated. A side entry rectangular light guide 50 is provided in the stud mount shown in Fig. 5, the internal end 53 of the guide being chamfered to provide light entry reflecting surface. The light guides may terminate in a lens element. The stud mount may be formed wholly of copper, or comprise a copper heat sink attached to a leadfree steel base and stem.
