LASER LIGHT SOURCE MODULE AND LASER LIGHT SOURCE DEVICE

The present invention provides laser light source modules capable of being densely disposed and also provides a laser light source device including a plurality of laser light source modules densely mounted therein. The laser light source module (100) includes: a plate-shaped stem (1); a power supply lead pin (2A, 2B) having an upper end protruding from an upper surface being one of main surfaces of the stem and a lower end penetrating to extend toward a lower surface side, the lower surface being the other of the main surface of the stem; a block (3) fixed to the upper surface of the stem; a submount substrate (4) that is fixed to a surface of the block and includes the semiconductor laser array (5) mounted thereon, the surface being parallel to the upper surface of the stem; the semiconductor laser array located on the submount substrate such that a light emitting direction is parallel to the upper surface of the stem; and a collimator lens array (6) that is located on a front surface of the semiconductor laser array and converts an output light beam of the semiconductor laser array into a parallel light beam.
