Embodiments include a laser pumping unit and a high power vertical external cavity surface emitting laser (VECSEL) device including the same. The laser pumping unit easily diffuses current in a traverse direction by using a tunnel junction. The laser pumping unit may include a substrate, a lower distributed brag reflector (DBR) layer formed on the substrate, an active layer with a quantum well structure formed on the lower DBR layer to generate a light having a predetermined wavelength, a tunnel junction layer formed on the active layer to increase resistance in a vertical direction, and an upper DBR layer formed on the tunnel junction layer.
