Abstract

Room-temperature continuous-wave operation of II–VI Hue-green laser diodes has been possible with a lifetime exceeding an hour.1 Some major problems limiting a long life-time for II–VI blue-green lasers are a high pre-existing defect density and the growth of defect density during laser operation.2 Recently, we proposed a theoretical model3 with an analytical solution for the degradation mechanism of II–VI LEDs based on the carrier-recombination-enhanced defect generation. Our model shows that the time dependence is nonexponential in character and its long-time behavior has a 1/t dependence.
