Title:
SEMICONDUCTOR LASER MODULE, LIGHT SOURCE UNIT, LIGHT SOURCE DEVICE, AND OPTICAL FIBER LASER
Document Type and Number:
WIPO Patent Application WO/2021/010488
Kind Code:
A1
Abstract:
Provided are a semiconductor laser module, a light source unit, and a direct diode laser which are highly reliable and can be miniaturized. A semiconductor laser module 10 of the present invention comprises: a semiconductor laser element 11 which outputs a multimode laser beam; a reflector 13 having a paraboloid 13a that collimates the laser beam in the vertical direction; and a package housing 15 having a mounting surface on which the semiconductor laser is mounted, and a window portion 16 through which a laser beam collimated by the reflector 13 is transmitted. The mounting surface of the package housing 15, on which the semiconductor laser is mounted, is a heat dissipation surface, and the window portion 16 is provided on a surface facing the mounting surface.
