半导体激光模块
摘要：
半导体激光模块(100)具备：半导体激光元件(104‑1～6)，其输出激光；光纤(112)，其具备芯部、和形成在芯部的外周的包层部，从一端入射所述激光，将该激光导波到该半导体激光模块的外部；光学部件(116)，其配置在所述光纤的外周，将所述光纤固定；第1固定剂，其将所述光学部件和所述光纤粘固；光吸收体(117)，其配置在所述光学部件的外周，将该光学部件固定；第1光阻断部(113)，其配置在所述光纤的所述激光的入射端与所述光学部件之间；和筐体(101)，其在内部收容所述半导体激光元件、所述光纤的入射所述激光侧的一端、和所述第1光阻断部，所述光学部件在所述激光的波长下有光透过性，所述光吸收体在所述激光的波长下有光吸收性。由此提供可靠性高的半导体激光模块。
摘要（英）：

A semiconductor laser module (100) includes a semiconductor laser element (104-1 to 6) outputting a laser light; an optical fiber (112); an optical component (116) disposed at an outer periphery of the optical fiber and fixing the optical fiber; a first-fixing agent (119) fastening the optical component and the optical fiber; a light-absorbing element (117) disposed at an outer periphery of the optical component and fixing the optical component; a first light-blocking portion (113) disposed between an end into which the laser light is incident of the optical fiber and the optical component; and a housing (101) 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.
