根据现有的材料参数，计算了Ｉｎ０．２Ｇａ０．８Ｎ／Ｉｎ０．０５Ｇａ０．９５Ｎ量子阱激光器的增益、阈值电流密度以及阈值与温度的关系。理论分析表明氮化物蓝绿光激光器的阈值电流密度是ＧａＡｓ材料的５倍以上，但其特征温度可接近５００Ｋ。
Based on the existing material parameters, the gain, threshold current density and the relationship between threshold and temperature of In0.2Ga0.8N / In0.05Ga0.95N quantum well laser are calculated. The theoretical analysis shows that the threshold current density of nitride blue-green laser is more than 5 times that of GaAs, but its characteristic temperature can approach 500K.
