A comparison of the wavelength shift of the vertical external-cavity surface-emitting laser (VECSEL) spectrum with increasing pump power reveals silicon carbide to be a far superior heat spreader material to previously used sapphire. We have demonstrated 0.5W with no rollover from a GaAs VECSEL by utilising an intra-cavity silicon carbide heat spreader. We believe that with increased pump power, the use of silicon carbide heat spreaders will provide a useful expedient to extend the available output power of VECSEL systems.
