Patent

CA 2333498

There is provided a semiconductor laser device capable of increasing the optical output. The semiconductor laser module comprises a semiconductor laser device (1), an optical fiber (2) that receives light emitted from the semiconductor laser device (1) and a photo diode (3) that monitors optical output of the semiconductor laser device (1). The optical fiber (2) is a lensed fiber having a wedge-shaped lens on its tip and the photo diode (3) placed in the vicinity of the laser light receiving end (2a) of the semiconductor laser device (1) receives reflected light from a reflection surface (2a1) and monitors the optical output of the semiconductor laser device (1).
