THE OPTIMIZATION OF REFLECTIVITY ON END SURFACE OF SEMICONDUCTOR LASER

本文从半导体激光器的速率方程组出发,分析了半导体激光器端面反射率的变化对其输出光功率的关系。数值计算表明,在对半导体激光器端面反射率进行优化后,能够获得最佳输出功率。此外,还分析了端面反射率优化后对半导体激光器微分功率特性的影响。

From the equation of velocity of semiconductor laser, we explain the relation of varity of reflectivity on end surface of semi-conductor laser with export power. The digit calculation shows that the best export power can be obtained after the optimization of reflectivity on end surface of semiconductor laser. By the way, we also analysed to have influence on the character of differential power of semiconductor laser after the optimization.
