ABSTRACT:
In a semiconductor laser device, a plane of polarization of a laser beam emitted by a semiconductor laser (4) is inclined from a substrate surface (4A), allowing the semiconductor laser (4) to be higher in power and higher in reliability. Moreover, a die-bond surface (17) of this semiconductor laser (4) is inclined by a specified inclination angle θ with respect to the reference surface (3) of the stem body (1), so that the plane of polarization of the laser beam can be made generally parallel to the reference surface (3) of the stem body (1). Thus, there can be provided a semiconductor laser device which is capable of contributing to a thinning of an optical pickup device and easy to manufacture.
