Abstract
The development of near ultraviolet laser diodes based on the AlGaN materials system on single crystal GaN substrates is presented. This includes growth of relaxed Ga-rich AlGaN layers, design of UV laser diodes, as well as discussion of the electrical and optical properties. We show that with the demonstration of optically pumped lasers, a pathway toward electrically injected laser diodes is available.
