Semiconductor laser module and method for manufacturing same

摘要

A semiconductor laser module includes a laser diode array, an optical fiber array, a fiber array fitting for fixing the optical fiber array, a casing, and a support fitting for fixing the fiber array fitting and casing. The fiber array fitting and support fitting have a first contact section that is in line-contact or surface-contact with the plane section parallel with the light emission surface of the laser diode array, and are laser-welded and fixed to each other at the first contact section. The support fitting and casing have a second contact section that is in line-contact or surface-contact with the plane section vertical to the light emission surface of the laser diode array, and are laser-welded and fixed to each other at the second contact section.
