ABSTRACT:
To provide a semiconductor laser device that is capable of outputting high power laser light and is suitable for optical recording, optical communication, welding, and the like, and a multiple wavelength laser light emitting apparatus employing the semiconductor laser device. The semiconductor laser device includes an optical element that at least partially reflects a laser beam emitted from an end face of a laser light oscillator in a semiconductor laser array element so that the laser beam is incident on another laser light oscillator. Due to this, even when laser light oscillators are disposed with such a pitch that does not pose problems in manufacturing, a laser beam emitted from an end face of one laser light oscillator and a laser beam emitted from an end face of another laser light oscillator are phase-locked. By condensing these laser beams, the semiconductor laser device can output higher power laser light than conventional.
