Abstract

We fabricated high-power pure blue laser diodes (LDs) by using GaN-based material for full-color laser display. The operating output power, voltage and wall-plug efficiency of the LDs at forward current of 1.0A were 1.17W, 4.81V and 24.3%, respectively. The estimated lifetime of the LDs was over 30, 000 hours under continuous-wave operation.
