Abstract :
A lasing wavelength of 480.5 nm for a II-VI laser diode (LD) has been realised. The threshold current of this blue LD is 470 mA. The threshold current of the II-VI LD, whose lasing wavelength is 495 nm, is ~100 mA. The light output power of the 495 nm LD is 600 mW and the slope efficiency is 0.63 W/A. These values are the best so far reported in a II-VI LD
