ABSTRACT:
A semiconductor laser module includes a flat board, a semiconductor laser, a lens, an optical fiber, a lens holder, an electronic cooling element, and support rods. The semiconductor laser is mounted on the board, and the laser emit a laser beam. The lens focuses the laser beam from the semiconductor laser. The optical fiber is optically coupled to the lens to receive the laser beam emitted from the semiconductor laser and focused by the lens. The lens holder holds the lens on the optical axis of the semiconductor laser. The electronic cooling element adjusts the temperature of the semiconductor laser, and the board is fixed to the upper surface of the electronic cooling element. The support rods support the lens holder at a position opposing a light-exit end face of the board.
