LASER DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

A laser device (100) of the present invention includes: a semiconductor laser element (2) having an output surface (2a) via which laser light is outputted; an optical fiber (4) having a leading end portion (4a) facing the output surface (2a) of the semiconductor laser element (2); and an optical fiber supporting member (5) for supporting the optical fiber (4), the optical fiber supporting member (5) being made from a non heat insulating material and having a bonding pad (7) to which the optical fiber (4) is fixed by use of solder (8). The optical fiber supporting member (5) includes a contact portion thermally in contact with a base (1). The bonding pad (7) is (i) spaced apart from the contact portion so as to be located on a side opposite from the contact portion so that a region to which laser light is applied from another laser element when the optical fiber (4) is fixed to the bonding pad (7) is sandwiched between the bonding pad (7) and the base (1) and (ii) separated spatially from the base (1).
