In this study, we measure the output current of a silicon-based positive-intrinsic-negative (p-i-n) quadrant photodetector (QPD) exposed to a millisecond-pulse laser radiation. We study the output current curve for a cell at different laser energy fluences and pulse widths. The results obtained show that the behavior of the output current involves a holding current stage as the photo-generated current stage declines with time. Based on these results and the p-i-n structure, we analyze such a behavior.

基于硅的偏置象限光电探测器中毫秒激光脉冲所产生的输出电流的深入研究

在这项研究中，我们测量暴露于毫秒脉冲激光辐射的硅基正本征（引脚）象限光电检测器（QPD）的输出电流。我们研究了在不同激光能量注量和脉冲宽度下电池的输出电流曲线。获得的结果表明，随着光生电流级随时间下降，输出电流的行为涉及一个保持级。基于这些结果和引脚结构，我们分析了这种行为。
