Developed in the late 90s, vertical-external-cavity surface-emitting lasers combine the high output power of the edge-emitting diode lasers with the excellent beam quality of the surface-emitters. In addition, the external-cavity design offers additional advantages, faciliating frequency mixing applications as well as the operation of the device in a pulsed regime. Here, the high-power potential of the vertical-external-cavity surface-emitting lasers is discussed. Different cooling concepts are studied and the limits of the power-scaling are investigated by spacially resolved temperature measurements.
