Abstract Changes in both surface morphology and transient reflectance on the front facet of a diode laser are monitored during a catastrophic optical damage (COD) process in a single pulse operation. Use of a 1550 nm time-resolved micro-reflectance optical system (with time resolution of ~4 ns) allows us to monitor the creation sequences of up to four distinct COD seed points on an 808 nm laser facet within a period of

通过反射分析监测 808 nm 激光二极管中的缺陷产生顺序

摘要 在单脉冲操作的灾难性光学损伤 (COD) 过程中，对二极管激光器正面的表面形貌和瞬态反射率的变化进行了监测。使用 1550 nm 时间分辨微反射光学系统（时间分辨率约为 4 ns）使我们能够在 808 nm 激光面上监控多达四个不同 COD 种子点的创建序列。
