Abstract
A semiconductor laser device comprising a semiconductor laser chip emitting infrared laser beams in a predetermined direction and a visible light source emitting visible light beams in the same direction. The semiconductor laser chip and the visible light source are disposed close to each other on a package stem. An optical element is disposed in a direction where both light beams are emitted so as to collimate or converge the visible light beams while allowing the infrared laser beams to pass therethrough without change. By this configuration, the operator can visually locate the infrared laser beams by knowing the location of the visible light beams.
