ABSTRACT A semiconductor laser module comprises a semi- conductor laser chip for emitting a laser beam, a collimator lens for collimating the laser beam to a collimated beam, a focussing lens for focussing the collimated beam, and an optical fiber having an inclined input face to which the laser beam from the focussing lens in input. The focussing lens is arranged in such a manner that the optical axis of the collimated beam incident on the focussing lens is deviated from a center axis of the focussing lens, and the optical fiber is arranged in parallel to the collimated beam in such a manner that the laser beam is incident on an optical axis of the optical fiber.
