半導体レーザーダイオード
Document Type and Number:
Japanese Patent JP4465295
Kind Code:
B2
Abstract:
Disclosed herein is a semiconductor laser diode to be assembled with a holder centrally perforated with an insertion cavity. The laser diode comprises a laser device, a frame unit, a resin unit, and at least one air passage. The resin unit includes a resin frame formed on the frame unit to surround the laser device while forming a light emission aperture. The air passage is formed at a surface of the resin frame perpendicular to an optical axis of a laser beam emitted through the light emission aperture, thereby defining at least one air channel between the resin frame and the insertion cavity in an assembled state with the holder. The air channel, defined at a boundary between the resin unit and the holder, is used as an outside air inflow and outflow passage, causing an improvement in heating source cooling and heat radiation characteristics of the laser diode.
