ABSTRACT:
The present invention provides a semiconductor laser devices of hologram laser type, constructed so that the configuration of the optical elements barely changes even if its package expands due to a rise in temperature or moisture absorption. In the semiconductor laser device, a body frame made of an insulating resin contains a semiconductor laser element, a mirror, a photo-detecting element for reading signals, a mirror-mounting base and a detector-mounting base. Also, a holographic element is mounted on the top of the sidewall of the body frame. The mirror-mounting base and the detector-mounting base are made of a resin, wherein each base is integrally formed with the base plate of the body frame and is separated from the sidewall of the body frame.
