| 摘 要： | 通过测量光伏型锑化铟探测器在不同功率密度、不同辐照时间的CW CO2激光辐照时性能的变化,得到其破坏阈值区间.理论上用一维热模型计算了探测器在激光辐照过程中的温升,结果表明,PV型InSb探测器的破坏效应源于连续波激光辐照过程中温升达到InSb材料熔点时其pn结退化为电阻.

| Abstract: | The performance of PV type InSb detector illuminated by CW CO2 laser with different power density and time duration has been measured so that the damage threshold range of 72W/cm2×(4～5)s is obtained.Based on one-dimension thermal model,thermal increase is theoretically calculated with the detector illuminated by laser.Results show that the detector damage source is the temperature in the proccess of CW laser illumination which gets up to the melt point of InSb so that its p-n junction becomes a resistance. |
