High‐power red laser diodes are essential light sources for display applications. In this paper, we report the design, fabrication and characterization of single‐emitter 638nm laser diode with 4 W continuous wave power. The saturation and COD power of this 110um stripe width LD exceeds 4.0 W and 6.3 W at heatsink temperature of 20°C, respectively. At the operation power of 1 W, the Wall‐Plug efficiency can reach 38.3% and 41.8% for the continuous and pulsed wave with duty of 33.3%. The characteristics temperature T0 and T1 for this device is 62 K and 114K.
