Abstract: A light source device includes a substrate, an edge-emitting laser element, a surface-emitting laser element, and an optical member. The substrate has a supporting surface. The edge-emitting laser element is directly or indirectly supported by the supporting surface and configured to emit a first light beam in a first direction. The surface-emitting laser element is directly or indirectly supported by the supporting surface and configured to emit a second light beam in a second direction different from the first direction. The optical member is configured to receive the first light beam and the second light beam and to cause the first light beam and the second light beam to exit the optical member as light beams traveling along a same axis.
