分析了影响增益饱和特性的几个因素：有源区截面积，顶层镜面反射率，泵浦功率，自发辐射因子。

Several factors affecting properties of gain saturation are analyzed, which are active region area, top mirror reflective, pump power, spontaneous emission factor,.

这是另外一个石膏像，表面覆盖有银色铝粉。这样表面的反射率就越强，越趋向于镜面反射。

Here's another casting of the plaster head covered with silver aluminum powder. The surface now has a high level of "specularity" or reflectivity.
