Semiconductor laser device |
摘要 |
A semiconductor laser device is provided which includes: a metallic main plate to which a laser diode chip is fixed through a sub-mount incorporating a photo diode and which serves as an electric common for these diodes; three metallic posts that are electrically connected by wires to the main plate, laser diode chip and photo diode, respectively, and are spaced apart from the main plate; and a resin case in which the laser diode chip and sub-mount are sealed and to which fixing end portions of the main plate are fixed. The resin case secures the main plate and the three posts in position such a way as to avoid direct contact therebetween.
