| 摘 要： | 用连续波DF激光辐照PV型HgCdTe红外探测器，得到不同辐照功率密度下，探测器响应输出的一系列实验结果，观察到器件饱和以外的如探测器混沌、探测器单极化等一些新现象，这些结果与理论预期有着较大差别。给出了实验结果的初步解释，该实验结果为今后更好地研究PV型HgCdTe探测器提供了新的线索。

| Abstract: | A continuous wave DF laser was induced on the PV HgCdTe infrared detectors, under various power density ,the detectors had a serious of output. With the increasing of irradiated laser power density, firstly the detector worked in linear section, then chaos occurred (laser power density about 334mW/cm2) , lastly unstable detector homopolarization was observed(laser power density about 14W/cm2),and the detector recovered to normal working status after the laser was removed. Some explanations about the results were given, as the results were very different from the theoretic expectation, they provide valuable clue for future research on PV HgCdTe. |
