PHN.9511 8 30.5.80 ABSTRACT "Semiconductor laser device" A semiconductor laser device comprises a support consisting of a substantially annular assembly block of a metal having a good thermal conductivity, which assembly block comprises positioning means on its outer circum- ference and furthermore comprises a sector-shaped suppor- ting part which extends towards its centre line and which has a connection face for a laser element extending through the centre line and determined accurately with respect to the positioning means. A base having mutually insulated electrical conductors and a photodiode is secured on the side of the assembly block remote from the supporting part, the cap comprising a light-transmit- ting window being secured to the assembly block on the other side so as to form a hermetic envelope.
