Abstract
A semiconductor laser device and optical pickup in which the reflectance of the side beam at a header portion will not adversely affect the characteristics of the optical pickup, and superior in productivity, and a method of fabricating such a semiconductor laser device are obtained. A reflector is attached on a side beam incident region of a leading end plane of a header mounted with a laser chip that emits a laser beam. Said side beam is one of the two side beams generated by the reflected ±first order beams and fed back through the optical system returning towards the header portion to strike the side beam incident region. The reflector reflects side beam outside the optical system.
