摘要	A semiconductor laser module has a Fabry-Perot type semiconductor laser device, an optical fiber, and first and second lenses. The tip of the optical fiber, on which the laser beam falls, is askew polished. The optical fiber is fixed in such a manner that the axis of the optical fiber makes an angle with respect to an optical axis of the laser beam. Coatings that avoid reflection are formed on the tip of the optical fiber, and on the first and second lenses.
其他摘要	半导体激光器模块具有法布里 - 珀罗型半导体激光器件，光纤，以及第一和第二透镜。激光束落在其上的光纤尖端被抛光。以这样的方式固定光纤，使得光纤的轴相对于激光束的光轴成一角度。避免反射的涂层形成在光纤的尖端上，以及第一和第二透镜上。
主权项	A semiconductor laser module comprising: a Fabry-Perot type semiconductor laser device; an askew incident surface optical fiber, wherein a laser beam emitted from the semiconductor laser device is incident; and an isolator positioned between the semiconductor laser device and the incident end of the optical fiber, wherein: the semiconductor laser module is used as the source of a forward excitation light of a Raman amplifier and the semiconductor laser module does not have a fiber grating, the laser beam includes not less than 2 oscillation longitudinal modes within a half width of an oscillation wavelength spectrum, and the isolator has a structure of at least 5 stages with a deflector/a Faraday rotator/a deflector being set as one stage, and the isolator is arranged to be inclined relative to the optical axis by about 40°.
