Abstract: A laser module according to the present disclosure includes a laser diode, a first collimating lens, and a beam twister. The laser diode includes a plurality of emitters and emits laser light from each of the plurality of emitters through a light emission surface. The first collimating lens is provided at a first distance from the light emission surface of the laser diode and parallelizes a fast-axis-wise divergence of the laser light. The beam twister is provided at a second distance away from the first collimating lens and turns the laser light approximately 90 degrees. Each of the plurality of emitters has a width of 5 μm to 120 μm on the light emission surface. The plurality of emitters have a pitch of 295 μm to 305 μm on the light emission surface.

Abstract: 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.
