Abstract:
1. A semiconductor laser device comprising: a semiconductor laser element for generating a laser beam; a photo-detecting element for receiving the laser beam reflected by an external optical storage medium; a holographic element for guiding the laser beam generated by the semiconductor laser element to the outside and for guiding the laser beam reflected by the optical storage medium to the photo-detecting element; a body frame made of resin having a base plate and a sidewall extending along the edge of the base plate, in which the semiconductor laser element and the photo-detecting element are contained in a space formed by the base plate and the sidewall, and the holographic element is mounted on a top of the body frame; and a lead frame extending from the outside of the body frame into the space formed by the base plate and the sidewall and being electrically connected to the semiconductor laser element and the photo-detecting element, wherein: the photo-detecting element is mounted on a detector-mounting base which is integrally formed with the base plate so as to protrude upward therefrom; and the detector-mounting base is separated from the sidewall of the body frame.
