摘要

理论分析和实验研究了高功率CO

激光对远场光导型长波红外HgCdTe探测器的干扰损伤。采用激光辐照探测器的温升理论模型，根据实验参数，讨论了高功率激光对长波红外探测器的损伤机理，计算了温升与辐照时间和功率的关系，并和CO

激光器在距离15 km处辐照光导型长波红外HgCdTe探测器的实验结果进行对比分析。实验结果表明，2.5 kW连续CO

激光经过大气衰减后在15 km处激光功率密度可达0.161 W/cm

，计算可知此时会聚到探测器靶面处的功率密度为140 W/cm

；靶面处功率密度为20.5 W/cm

时，对探测器产生干扰；靶面处功率密度为110 W/cm

时，达到损伤，计算此时探测器表面温度已达到Hg析出温度，这一实验现象和理论计算预期结果相吻合。实验结论对研究探测器的激光防护和激光干扰星载探测器技术具有指导意义。

Abstract

The high-power CO

laser disturbance to Long-wave Infrared (LWIR) HgCdTe detectors is investigated theoretically and experimentally in this paper. Based on the practical parameters of experiments

a theoretical model of temperature-rise is adopted to calculate the variation of temperature with the time and the power of laser irradiation on a detectors. Then

the high-power laser damage mechanism to the LWIR detector is discussed

and obtained results are compared with the experimental results from that a CO

laser irradiates the detector on the distance of 15 km. The experimental results show that the power density of the CW CO

laser with the power of 2.5 kW can achieve 0.16 W/cm

after attenuation for 15 km distance. Therefore

the power density of the target after focusing by a lens can be 140 W/cm

by calculation.Furthermore

when the power density of the target is 20.5 W/cm

the detector can be jammed; when it achieves 110 W/cm

the detector can be damaged and the detector temperature is high enough for Hg deposition. This experimental phenomenon well agrees with the results predicted by the theoretical calculation. The conclusions can provide references for the laser defense of detectors and laser jamming satellite-based detectors.
