Laser diodes and bars with high efficiency, power, and reliability are critical for a wide variety of applications including direct material processing and pumping high power and efficient fiber lasers and solid state lasers. We present progress towards the 80% power conversion efficiency goal of the DARPA Super High Efficiency Diode Sources (SHEDS) program. Currently using JDSU SHEDS technology, laser bars and stacks respectively achieve as high as 76% and 73% total power conversion efficiency at room temperature. Single-emitter laser diodes incorporating SHEDS technology achieve up to 19W peak CW power from a 100um wide aperture.
