摘要
对3.8μm激光破坏三元PC型HgCdTe探测器系统的实验结果进行定性分析。实验结果表明:当辐照在探测器系统上的激光功率密度达411W/cm2时,系统内各部件(Ge窗口、滤光片及探测器)已严重损坏,探测器系统永久失效。分析认为:实验中引起探测器系统破坏的主要原因是温度升高引起的烧蚀热。
In this paper, the experimental results that detector system of three PC HgCdTe units is destroyed by 3.8μm laser are reported and analyzed qualitatively. Researches indicate that components of detector system which are Ge window, filter and detectors are destroyed when laser power density reaches 411W/cm^2. Analyses show ablation heat is the most important reason of detector system damage in this experiment.
