High-power pure blue laser diodes (LDs) are expected to be adapted to the light sources for full color laser display systems. We have succeeded in fabricating high-power blue LDs by optimizing the structure of ridgewaveguide LDs. The typical operating current, voltage and wall-plug efficiency of these LDs with an optical output power of 500mW were 480mA, 4.8V, and 21.7%, respectively. After 5,000 hours operation, the lifetime was estimated to be over 30,000 hours.
