Surface emitting laser module, optical scanner, and image forming apparatus

摘要

Disclosed is a surface emitting laser module including a surface emitting laser element formed in a semiconductor substrate and having a surface emitting laser array (20) that emits light in a direction perpendicular to a surface of the semiconductor substrate; a package (10) having a region in which the semiconductor substrate is provided; and a metal cap (50) having a cylindrical part (53) formed of metal, the cylindrical part (53) having a transparent substrate (52) on one side thereof and a bottom part (54) on the other side thereof bonded to the package (10). The transparent substrate (52) is provided in the metal cap (50) in such a manner as to be inclined with respect to the semiconductor substrate, the package (10) has a metal part at a bonding part thereof bonded to the metal cap, and the metal part (50), and the metal cap are bonded together by welding.
