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.
