Abstract :
Highly efficient quantum well laser diode is promising as a red light source for laser display. In the wavelength range of red light, short lasing wavelength is preferred because spectral luminous efficiency increases sharply as wavelength shortens. In this paper, we present high-power AlGaInP laser diode with remarkably short lasing wavelength of 625 nm. The fabricated device showed 220 mW and 44 lm output at 25 °C under CW operation. Efficiency was measured as 24 lm/W. Comparisons to 630-nm and 638-nm laser diodes are also presented.
