Abstract:
1. A semiconductor laser assembly comprising: a semiconductor laser device including a semiconductor laser element, a lead-frame on which the semiconductor laser element is provided, an enclosure with an opening to project laser beams from the semiconductor laser element to enclose the semiconductor laser element and a spring member of a plate like material; and a heat dissipation member having inside walls to define a perforation to receive the semiconductor laser device, wherein the spring member is provided with a holding portion extending along an outer surface of the enclosure from the lead-frame and is provided with spring portions of a bent structure with spring to push one of the inside walls of the heat dissipation member and the semiconductor laser device by repulsion, so that the semiconductor laser device is configured to further push another one of the inside walls positioned on a back side of the enclosure to hold the semiconductor laser device in the heat dissipation member, and wherein the holding portion holds the back side and side walls of the enclosure, the holding portion is folded to direct the spring portions of the bent structure to the one of the inside walls of the heat dissipation member.
