Abstract
A semiconductor laser device and method of producing the same in which a laser diode chip is mounted on a stem via a heat sink. The cap is fixed to the stem covering the chip and includes a penetrating aperture, a lens for collimating light from the chip into penetrating aperture, and an optical fiber for guiding the collimated light which is fixed to the penetrating aperture after insertion to a desired depth.
