From the junction temperature-varied optical properties measurement, we find that the luminous efficiency will decay more quickly at low current operation. However, when the current density increases to the saturation capacity of the quantum well, the decay ratio will reach a constant.

在变温的光学特性量测上，由实验结果发现，发光效率在较低电流时会衰减的较快，然而在注入电流达到量子井的饱和量后，其发光效率随接面温度升高衰减的现象则会趋近於固定的比例。

More than 50 GaAs/GaAlAs High Power Single Quantum Well Semiconductor Lasers are aged. The threshold current decreases during the early aging (first 520 h) and the largest decrease is 57 mA.
