Patent ID: 8126026

Claim:
A semiconductor laser device comprising: a semiconductor laser element emitting laser light; a frame on which the semiconductor laser element is mounted; a resin-molded portion arranged on the frame, around the semiconductor laser element; and a submount between the semiconductor laser element and the frame, and the submount being wire-bonded to the frame, wherein a front edge of the frame is located frontward of a front edge of the resin-molded portion, is arranged on an optical axis of the semiconductor laser element as seen in a plan view, and is formed perpendicular to the optical axis, wherein a width of the entire front edge of the frame is smaller than a width of the front edge of the resin-molded portion, wherein the resin-molded portion is arranged to both sides of the semiconductor laser element, and has formed therein a laser output window open in front of the semiconductor laser element, wherein a width of the front edge of the frame is larger than a width of the laser output window, wherein a wire-bonded position is located where a wire leading from the frame is wire-bonded to the submount, and wherein the laser output window extends to the wire-bonded position with the same width of the laser output window along the optical axis and faces both sides of the semiconductor laser element.
