    摘要: A semiconductor laser module includes a semiconductor laser assembly formed by containing a semiconductor laser in a package, a lens assembly fixed by welding to the package of the semiconductor laser assembly, and a fiber assembly fixed by welding to the lens assembly. The semiconductor laser assembly includes a base fixed to the package and a carrier fixed to the base. The semiconductor laser is mounted on the carrier. A lens holder of the lens assembly is spot-welded to the package at a plurality of positions set below the upper surface of the base.

    摘要: A rod lens fixing method which can prevent the generation of cracks in a rod lens due to annealing to be carried out after welding a lens assembly. The rod lens fixing method includes the steps of providing a flanged split sleeve having an axial slit extending continuously from one end of the flanged split sleeve to the other end thereof, the axial slit being wide enough at least a flange of the flanged split sleeve to permit laser welding; press-fitting the rod lens into the flanged split sleeve; and applying a solder into the axial slit to solder the rod lens to the flange split sleeve. This method further includes the steps of inserting the flanged split sleeve into a bore formed at one end portion of a sleeve, the bore having a diameter larger than an outer diameter of the flanged split sleeve and smaller than an outer diameter of the flange; and laser-welding the flange to one end surface of the sleeve at a plurality of points on an outer circumference of the flange and in the axial slit. The laser welding in the axial slit of the flange causes the acting of shrinkage forces in the flange to thereby prevent the generation of cracks in the rods lens during the annealing.
