摘要
采用转换矩阵的处理方法,对大功率半导体激光器腔面光学灾变阈值与膜层结构的关系进行了分析。从理论上给出了膜层的设计方法和计算结果,解释了不同腔面反射率对应的腔光学灾变阈值变化的实验结果,并首次提出后腔面的优化结构以避免后腔面烧毁。
Using the transition matrix method, the relationship between the catastrophic optical damage threshold and the coating structure of semiconductor lasers were analyzed. A design method of coating structure and the calculated results were offered theoretically. The variety of catastrophic optical damage threshold along with different facet reflectivity was explained. The optimized structure of the rear cavity facet avoiding the damage of the rear facet was offered for the first time.
