A potential laser jamming and damage to satellite-borne photoelectric detector by means of combined fiber lasers is proposed. Through the analysis of the photo-electromotive force of a HgCdTe photovoltaic detector it was shown that the combining of fiber lasers with an output power of 100W was sufficiently powerful to completely laser jam a HgCdTe photoelectric detector through optical saturation. The laser-induced temperature rises under single-pulse-irradiation and continuous wave (CW) irradiation were developed. A temperature rise of 1000K was achieved after 5ms with CW laser irradiation. The damage thresholds under single-pulse-irradiation and continuous irradiation were calculated and showed that the combined fiber lasers produced enough power to completely laser jam a satellite borne photoelectric detector by inflicting both “soft damage” and “hard damage”.
