Watt-class AlInGaN blue and green laser diodes (LDs) on c face GaN substrate are fabricated. The optical output powers of blue LDs and green LDs were 3.75 W and 1.01 W, and the wall plug efficiencies were 38.5% and 14.1%, respectively. The lifetimes were estimated to be over 30,000 and 15,000 hours at a case temperature of 50°C.
