Abstract
We report on an optically pumped vertical-external-cavity surface-emitting laser diode coupled by a high reflectance volume holographic grating (VHG). The major feature of such a system is very narrow linewidth and high degree of power scalability, required for pumping upper energy levels of a gain medium. The cavity design lends itself to scaling to 2D VECSEL arrays suitable for low cost, high brightness pump sources.
