Abstract

A semiconductor laser module includes a semiconductor laser element outputting a laser light; an optical fiber; an optical component disposed at an outer periphery of the optical fiber and fixing the optical fiber; a first-fixing agent fastening the optical component and the optical fiber; a light-absorbing element disposed at an outer periphery of the optical component and fixing the optical component; a first light-blocking portion disposed between an end into which the laser light is incident of the optical fiber and the optical component; and a housing accommodating therein the semiconductor laser element, an end into which the laser light is incident of the optical fiber and the first light-blocking portion. The optical component has an optical transmittance at a wavelength of the laser light, and the light-absorbing element has an optical absorptivity at a wavelength of the laser light.
