摘要	To explore the mechanism of damage caused to a HgCdTe infrared detector by a long-wave infrared laser, the damage caused by a 9.3 m laser to an HgCdTe infrared detector was experimentally analyzed. A finite element simulation model of the HgCdTe infrared detector irradiated by the laser was established in ANSYS. The temperature rise distribution of the detector model under CO2 laser irradiation with a 9.3 m pulse was obtained. The theoretical damage threshold of the detector was determined based on whether the melting temperature had been reached. Subsequently, the damage threshold of an HgCdTe infrared detector in an actual working environment was determined through field experiments. The results show that the damage threshold is 0.54-1.1 J/cm2. The simulation results, which predict a damage threshold of 0.69-1.23 J/cm2, and the experimental results are in agreement with the Bartoli theory and are thus considered to be valid. 2021 Science Press.
