High brightness directed energy lasers based on combining beams generated by fiber lasers and amplifiers require fiber-coupled 976 nm diode laser pumps with spatial and spectral brightness that exceed current state-of-the-art. We will meet these requirements by adapting 1060 nm MOPA designs with which we have demonstrated operation at brightness approaching 1 GW/cm^2*sr, to 976 nm.
