Optical ranging device, laser light emitting device, and method for manufacturing the same

A laser light emitting device configured to emit laser light, comprising:

• a semiconductor laser element provided with a plurality of light emitting regions, wherein
• a length of each of the light emitting regions of the semiconductor laser element in a first direction is more than a length thereof in a second direction intersecting the first direction, and
• adjacent light emitting regions included in the plurality of light emitting regions are separated from each other in the second direction and abut or overlap each other in the first direction.

A method of manufacturing a laser light emitting device, comprising:

• preparing a plurality of light emitting sections, wherein each of the light emitting sections is prepared by stacking a semiconductor layer on a substrate and forming a light emitting region, and a length of the light emitting region in a first direction, which is a layer direction of the semiconductor layer, is more than a length thereof in a second direction, which is a stacking direction of the semiconductor layer, and
• arranging the light emitting sections such that the light emitting sections are separated in the second direction, and the light emitting regions of the light emitting sections abut or partially overlap each other in the first direction.
