    摘要: Embodiments provide a vertical external cavity surface emitting laser (VECSEL) that may provide a uniform current density in an active layer using a double current injecting channel. The surface emitting laser device may include a double channel current injection structure for uniformly applying current to an active layer, wherein the double channel current injection structure may include: a first current injection channel, which may allow current to be injected toward a central portion of an aperture, which may be a light beam output region formed in the active layer, and may have a smaller diameter than the aperture: and a second current injection channel, which may allow current to be injected toward an edge of the aperture and may be located around the aperture.
