52.3: High ‐ Power InGaN Blue ‐ Laser Diodes for Displays

We have developed high power blue laser diodes (LDs) with an emission wavelength of 445 nm by using GaN material. The operating current and voltage of these LDs at an output power of 200mW were 274 mA and 4.9 V, respectively. The estimated lifetime was over 10,000h under 25 °C continuous-wave operation at an output power of 200 mW.
