Provided is a pump laser integrated vertical external cavity surface emitting laser (VECSEL). The VECSEL may include a surface emitting laser unit including a first active layer having a multiple quantum well structure emitting light having a first wavelength, a reflective layer may be formed on the first active layer, and an external mirror may be disposed opposite to a lower surface of the first active layer and defining a cavity resonator together with the reflective layer. A pump laser unit may be formed on a part of the surface emitting laser unit and may have a perpendicular light emissive surface emitting a pump beam having a second wavelength for exciting the first active layer. A beam reflector may be formed on the light emissive surface of the pump laser unit and reflecta pump beam that is incident from the pump laser unit to the first active layer.
